Season 2B dropped yesterday and I've already watched all of it, so here be (semi-vague) spoilers.
This show is so dumb. It's enjoyable, but it's so dumb. Various characters had to hold the idiot ball this season to advance the plot, and it just left me shaking my head. Sure, let a nurse escort you out the hospital wing when you know another character was just about to tell you extremely important information! Sure, conveniently forget that your psychic artist friend literally labeled one of his drawings with the name of the dead curse-originator, and take the long route to finding her via manipulating a jailed ex and threatening a priest! Sure, you know you're predicted to die by crushing, so place yourself between a wall and a heavy automatic gate that's stuck halfway open! Sure, choose letting your trapped (but ultimately safe) friends out of a barn vs. chasing the psycho carrying the only thing you need to end the curse!
Speaking of the curse, I loved that it originated in 1988. The way they were talking about it, with this old witch-related game and demon possession and exorcisms and family farm cemetery plots, I assumed it had started 100+ years ago, but nope, 1988! It kinda makes sense with the Satanic Panic going on around that time, but it was still so amusing when the kids found that (VHS!) taped confession from the late '80s. So vintage. I'm surprised they knew how to play it!
I thought the acting was pretty solid, for the most part. Sometimes I'd think the actress playing McKenna was weak, but then she'd switch to Jennie and slightly change her voice, use different facial expressions, and even carry herself in a completely different way, and I remembered she was good. McKenna herself is a sad-sack "final girl"; the actress is fine.
Character development was probably the best aspect of the whole show. I went from hating Violet in season one to liking her more than any other character by the end of season two. I was also delighted that two of the characters who hated each other the most -- Violet and Alex -- were two of the closest by about 3/4 of the way through 2B, and it felt natural. I was almost shipping them by that point. Nobody felt shoehorned into the group, not even Sammi or Peri, who were appropriately arms-length with various other characters, choosing to prioritize their safety and the safety of their love interest over the safety of the other people they didn't know as well.
The ending was satisfying enough, I guess. I figured four of the characters would make it out okay, but a fifth one surprised me by slipping through. The final scene was... well, it was setting up season three. I wonder how long they can keep this franchise going with this group of characters, or if keeping the entire core group of five is even their plan.
