So Riverdale is such a hilariously perfect show for The CW. Watching it on Netflix recently and it checks all the box with a ridiculously good looking cast and over dramatic borderline nonsensical storylines. But it also comes across self aware. Not quite as self aware as say... MTV's Scream tv show, but it's nearly there. It also has the benefit of doing a pretty good job of executing the IP with a twist angle that it was pitched as.
Greg Berlanti just has this marvelous knack for these types of shows. A super fun aspect of these shows is that they cast older actors that were known for the genre when they were younger. In his Superhero shows, he casts actors from previous iterations of his characters (Mark Hamill, Dean Cain, John Wesley Shipp, Helen Slater, etc...) but since there were no live action Riverdale shows or movies to pull from, he instead goes into the vault of Teen Genre film and tv with a touch of Soap Opera as well... casting Skeet Ulrich, Luke Perry, Molly Ringwald, Marisol Nichols, Martin Cummins, Madchen Amick, Lochlyn Munro, and Robin Givens.
Now I wouldn't personally spend my Primetime hour watching this on broadcast... it makes for really good Netflix background trash tv viewing while knocking out chores.
Riverdale is pretty shit IMO. It doesn't get why any of the Archie characters work and they decided to erase one of the few asexual characters in fiction.
