So yeah, it ends with a whimper, just like season 1 and Jessica Jones. I wonder why all Netflix shows start so strong and then drop the ball in the last two or so episodes.
The ninja fights got boring quickly, The Hand was portrayed in a very unsatisfying way. So, who was its leader? Nobu? Certainly didn't seem such a powerful guy in the first season, when he basically did everything Fisk wanted. The hole isn't explained, the pale kids aren't completely explained, the black jar isn't explained either, even though we can guess what it's for by now, the immortality thing isn't explained. What about Black Sky? Really not well explained, starting from the first season's kid to the awful revelation about Elektra being a (the? Is BS one or several entities?) Black Sky. They noticed she was BS because she fought well? Really? Didn't even say what they need BS for.
Elektra's motivations and actions themselves are really poorly explained, it's like she jumps from a mood to the opposite one in a matter of minutes: first she's with Stick, then suddenly with Matt, then she flees, then she comes back, she wants to kill Stick, then she helps him, she embraces her evil part, then she doesn't. Come on.
I think they should've gone wild with the mystic stuff. I was genuinely interested but they kept half-assing it, showing some weird stuff without explaining jack shit. It's like they were scared of alienating season 1 fans or something, because the approach then was far more realistic and gritty. They made a huge mistake.
The Blacksmith stuff is extremely unsatisfactory, feels like there's more to the park shooting than what we know, yet they don't delve on it. Feels like the Punisher story hasn't reached any closure. We hear a bit about Karen's past, then we don't go there either. It's like a constant, unresolved, teasing, and I'm worried we won't get answers in the next season: do you remember Stone in the first season? One would have assumed that he'd be in season 2, but nope. Why teasing things so much in advance then?
Frank's apparition in the last episode was kinda crap, I was expecting him go all out with the damn minigun... but we got two rifle shots instead? And 3/4 of the ninja army suddenly disappeared?
Matt also comes off as seriously confused in regards to his love life: first he's all in with Karen, even plainly rejecting his ex, then it's over so quickly with Karen and in the last episode he's literally salivating over Elektra. Then she's dead and he's like "ah whatever", going back to Karen immediately and showing her the mask. At one point I even thought he was going to try something with Claire again.
