I definitely won't get visual temporary versions of the remaining episode guides ready before Sunday, so I'll just make text versions and put them on pastebin or something.

Season 6 controversially adds Starlight Glimmer as essentially a seventh main pony character. Similar to how Princess Twilight was handled, Starlight tends to appear only if the episode is specifically about her. Though the season as a whole isn't that different in quality from the previous, multiple significant episodes unfortunately are on the weaker end. We chose not to recommend them, instead just noting how they're important. This doesn't mean they're bad, so check them out if they interest you.
[GOLD]01-02. The Crystalling[/GOLD]
[IMAGE=http://mlp.wikia.com/wiki/File:Flurry_Heart_enjoying_Sunburst%27s_company_S6E2.png]
While the Mane Six travel to the Crystal Empire to meet Cadance and Shining Armor's new baby, Flurry Heart, Twilight convinces Starlight to reunite with her childhood friend, Sunburst. However, Starlight is anxious about how he'll react to what she did since they last met. Flurry is yet another alicorn, but people largely stopped caring by this point. This is the closest the show has gotten to a "slice of life" two-parter.
03. The Gift of the Maud Pie (Pinkie Pie, Rarity, Maud Pie)
[GREEN]+[/GREEN] Fun interactions with Maud, and in one scene, Rarity out-Pinkies Pinkie.
04. On Your Marks [SONG] (Apple Bloom, Cutie Mark Crusaders)
* [PINK]Establishes that the CMC now help other ponies earn and understand their cutie marks.[/PINK]
* The first episode to have none of the Mane Six, even as cameos. This appears to chronologically happen right after season 5's "Crusaders of the Lost Mark", unless the CMC really waited weeks for their next meeting.
[GREEN]+[/GREEN] Has Apple Bloom's first solo song, which is pretty good, and fun individual scenes.
[RED]-[/RED] The different parts don't connect well.
[PINK]05. Gauntlet of Fire (Spike, Ember, Twilight Sparkle, Rarity)[/PINK]
[IMAGE=http://mlp.wikia.com/wiki/File:Spike_extends_a_handshake_to_Ember_S6E5.png]
Spike is summoned to the Gauntlet of Fire, where dragons compete for the title of Dragon Lord. When he overhears competitors saying they'll attack Equestria if they win, Spike decides he can't let that happen.
* This follows up on season 2's "Dragon Quest", but all you need to know is that Spike encountered a mean teenage dragon named Garble.
[GREEN]+[/GREEN] Introduces Princess Ember, who was very popular with fans, and provides much-needed nuance to dragon society.
[GREEN]+[/GREEN] A Spike episode where he's competent the entire time, for once.
[GOLD]06. No Second Prances[/GOLD]
[IMAGE=http://mlp.wikia.com/wiki/File:Twilight_calling_out_to_Trixie_S6E6.png]
Twilight asks Starlight to make a new friend on her own, but when she chooses Trixie, Twilight worries she'll be a bad influence. Trixie appeared in season 1's "Boast Busters" and season 3's "Magic Duel", but she's finally made a recurring character here.
07. Newbie Dash (Rainbow Dash, Wonderbolts, Scootaloo)
* [PINK]Rainbow Dash finally joins the main Wonderbolts team, with the callsign Rainbow Crash.[/PINK]
[GREEN]+[/GREEN] Pretty funny episode, unless you don't like...
[RED]-[/RED] Cringe humor from Rainbow embarrassing herself while trying to get a better callsign. Compared to other goal-achievement episodes, oddly little weight is given to this.
[PINK]08. A Hearth's Warming Tail [SONG] (Starlight Glimmer, Mane Six)[/PINK]
[IMAGE=http://mlp.wikia.com/wiki/File:Spirit_of_HW_Past_%22every_little_bitty_choice%22_S6E8.png]
Hearth's Warming Eve is here once again in this full-musical episode. After Twilight learns that Starlight doesn't care about the holiday, she reads to her an Equestrian version of
A Christmas Carol.
[GREEN]+[/GREEN] Fun adaptation with fantastic songs, including Luna's first solo song. Has a top 10 cutest Twilight moment.
[PINK]09. The Saddle Row Review (Rarity, Mane Six)[/PINK]
[IMAGE=http://mlp.wikia.com/wiki/File:Rarity_%22I_just_have_two_other_boutiques%22_S6E9.png]
Rarity has opened a new shop in Manehattan and is ready to read the reviews, but her friends worry what she'll learn about how opening night really went. This episode follows the format of The Office and Parks & Rec, cutting back and forth between the opening night and interviews.
* Starting from this episode, Coco Pommel is only ever addressed as Ms. Pommel, for legal reasons.
[GREEN]+[/GREEN] The format makes for an unusual and hilarious story where everyone gets a chance to shine.
10. Applejack's "Day" Off (Applejack, Rarity, Twilight Sparkle)
[GREEN]+[/GREEN] Some funny moments, and some people like the relaxed pace and lesson about working efficiently.
[RED]-[/RED] When I say relaxed pace, I mean it spends minutes just on Applejack walking around the spa to find out why the steam room isn't heating up quickly.
[PINK]11. Flutter Brutter [SONG] (Fluttershy, Rainbow Dash, Mane Six)[/PINK]
[IMAGE=http://mlp.wikia.com/wiki/File:Fluttershy_confronting_her_brother_S6E11.png]
Fluttershy has had enough of her freeloading younger brother, Zephyr Breeze, and forces him to get a job.
[GREEN]+[/GREEN] Good showcase of Fluttershy's character development; from this point on, there are no more Fluttershy episodes about her being too shy. We get to see her parents, and Zephyr is pretty funny.
[RED]-[/RED] Though some find Zephyr annoying.
12. Spice Up Your Life [SONG] (Rarity, Pinkie Pie)
* Map episode for Rarity and Pinkie.
[GREEN]+[/GREEN] Fun Indian-influenced song, and interesting to see Rarity and Pinkie work together.
[PINK]13. Stranger Than Fan Fiction (Rainbow Dash, Daring Do)[/PINK]
[IMAGE=http://mlp.wikia.com/wiki/File:Rainbow_and_Quibble_angrily_face_off_S6E13.png]
Rainbow visits a Daring Do convention and befriends a pony named Quibble Pants, until she discovers he hates everything after book 3. A rift forms between them, but they must work together when they're swept up in a real Daring Do adventure. Quibble is voiced by comedian Patton Oswalt.
[GREEN]+[/GREEN] Hilarious episode filled with meta jokes, including a fan convention staple you wouldn't expect in a kid's show.
14. The Cart Before the Ponies [SONG] (Cutie Mark Crusaders, Applejack, Rarity, Rainbow Dash)
[GREEN]+[/GREEN] Catchy song, and other fun moments, including Cheerilee as a Cheerileader.
[RED]-[/RED] The adults act pretty dumb, and the cart racing isn't crazy enough.
15. 28 Pranks Later (Rainbow Dash, Mane Six)
[GREEN]+[/GREEN] Zombies! A pretty neat episode, as long as you keep in mind that...
[RED]-[/RED] Rainbow acts like it's season 1 again, reverting all of her character development. Has the same general story as season 2's "The Mysterious Mare Do Well" of all things, but it's better than that, at least.
16. The Times They Are a Changeling [SONG] (Spike, Thorax)
* [PINK]Introduces Thorax, a mild-mannered good changeling (season 2's "A Canterlot Wedding"), who plays a major role in the season finale.[/PINK]
[GREEN]+[/GREEN] Neat to learn more about changelings, and Spike and Thorax have nice scenes together. [PINK]Has Spike's first real solo song, "A Changeling Can Change".[/PINK]
[RED]-[/RED] Rushed resolution.
[PINK]17. Dungeons and Discord (Discord, Spike, Big Macintosh)[/PINK]
[IMAGE=http://mlp.wikia.com/wiki/File
iscord,_Big_Mac_and_Spike_LARPing_S6E17.png]
While Fluttershy and the others go on a trip, a bored Discord decides to join Spike and Big Macintosh in their "Guys Night". He's horrified when he discovers they spend it playing a role playing game, Ogres & Oubliettes.
[GREEN]+[/GREEN] Great comedy, not just from the guys, but also from Fluttershy not taking any crap. It's also nice to see Discord connect with someone besides her or Twilight.
18. Buckball Season (Rainbow Dash, Applejack, Fluttershy, Pinkie Pie)
[GREEN]+[/GREEN] Fun episode filled with adorable moments, including Smug Fluttershy. Demonstrates Rainbow's character development, and randomly makes Snails (from season 1's "Boast Busters" and other episodes) pretty cool.
[PINK]19. The Fault in Our Cutie Marks [SONG] (Cutie Mark Crusaders)[/PINK]
[IMAGE=http://mlp.wikia.com/wiki/File:Gabby_hugs_the_CMCs_S6E19.png]
The Cutie Mark Crusaders have settled into their new role, but they might have an impossible task when an excitable young griffon named Gabby asks them to help her get a cutie mark.
[GREEN]+[/GREEN] Good song, nice lesson, and Gabby was an instant hit with the fans.
[RED]-[/RED] Some found Gabby very annoying.
20. Viva Las Pegasus (Applejack, Fluttershy, Flim & Flam)
* Map episode for Applejack and Fluttershy.
[GREEN]+[/GREEN] Interesting new Las Vegas setting with fun visuals, including clever substitutions for gambling. Good use of characters.
[PINK]21. Every Little Thing She Does (Starlight Glimmer, Twilight Sparkle, Mane Six)[/PINK]
[IMAGE=http://mlp.wikia.com/wiki/File:Starlight_Glimmer_%22you_can_take_it_from_here%22_S6E21.png]
Twilight has Starlight spend quality time with her friends while she's away, and wishing to finish this quickly, Starlight uses a mind control spell on them, as you do. Of course, this goes out of control.
[GREEN]+[/GREEN] Hilarious episode with great character moments, demonstrating how Starlight still struggles with her previous villainous nature.
[RED]-[/RED] If you strongly feel that Starlight was forgiven too easily for her actions, or are concerned about power levels, then I have bad news for you.
22. PPOV (Pony Point of View) (Twilight Sparkle, Applejack, Rarity, Pinkie Pie)
[GREEN]+[/GREEN] Pinkie's story is funny, and Rarity's is hilarious thanks to Salty Sea Dog Applejack.
[RED]-[/RED] Boring Applejack tells her story last, and the explanation for what really happened is weird.
23. Where the Apple Lies (Apple Family, Rich Family)
* First episode besides "Cutie Mark Chronicles" to mostly take place years in a character's past.
[GREEN]+[/GREEN] Neat to see Ponyville years in the past, it's fun to see young Applejack and Big Mac, and the episode is a good "escalating lies" story with a great climax.
[PINK]24. Top Bolt (Twilight Sparkle, Rainbow Dash, Wonderbolts)[/PINK]
[IMAGE=http://mlp.wikia.com/wiki/File:Rainbow_Dash_%22two_of_the_greatest_flyers%22_S6E24.png]
The Map sends Twilight and Rainbow to the Wonderbolts Academy, where they find a promising pair of recruits who are holding each other back in their attempts to help the other.
* Map episode for Twilight and Rainbow. Has a cameo from a Make a Wish Foundation recipient: the recruit who tells Twilight and Rainbow that they are her favorite ponies.
[GREEN]+[/GREEN] Spiritual sequel to season 4's "Testing Testing 1, 2, 3", with great interactions between Twilight and Rainbow. The new characters are likable, and Vapor Trail in particular was popular with fans.
[GOLD]25-26. To Where and Back Again[/GOLD]
[IMAGE=http://mlp.wikia.com/wiki/File:Trixie_looks_to_Starlight_Glimmer_for_a_solution_S6E25.png]
Starlight returns to her village to attend a festival, only have a panic attack when they ask her to help organize it. When she returns to Ponyville, she discovers that everyone is acting strangely. She must team up with Thorax ("The Times They Are a Changeling") and other misfits to confront the source of this problem, and overcome her fear of reverting to her old self.
Equestria Girls: Legend of Everfree [SONG]
[IMAGE=http://mlp.wikia.com/wiki/File:Objects_float_in_Twilight_and_Sunset%27s_tent_EG4.png]
Canterlot High goes on a field trip to Camp Everfree, and the girls hope to take a break from their magic adventures there. Twilight (from the human world) in particular fears that she'll turn into Midnight Sparkle again if they encounter more magic. While there, they discover that the legendary monster Gaia Everfree is supposedly wrecking the camp, and they suddenly gain new uncontrollable powers.
* Doesn't tie into season 6 at all. Gives SciTwi her own love interest, who's better than Flash Sentry, at least. On a side note, oddly depicts Filthy Rich as a pure villain, despite "Where the Apple Lies" this very season presenting him as nice and reasonable.
[GREEN]+[/GREEN] This is the closest to a slice of life story the movies get, and it's pretty enjoyable when focusing on that. SciTwi has nice scenes with Sunset, and Flash Sentry gets dunked on even more than last time.
[RED]-[/RED] The Scooby Doo style main story isn't great, characters besides SciTwi and Sunset don't do much of note, and the new powers are amazingly useless.
