This show is weird. It's basically the CW trying to do Twin Peaks, except with Archie characters. And like I said, it's weird. Like, if Sabrina showed up with actual magic powers, I would be like "Sure! Makes sense!" and just go with it.
Basically, this season seems to be set around the mystery of who murdered Jason Blossom, with Jughead as a pretentious would-be hard-boiled narrator writing a book about this (which makes me seriously hope that the ultimate twist is that he did it in a Murder of Roger Ackroyd-style reversal. That, or the killer is the Punisher).
Meanwhile, in terms of the classic Archie/Betty/Veronica love triangle, this show seems to be putting way more emphasis on Betty and Veronica actually being friends, while (aside from an unconvincing "Seven Minutes in Heaven" scene) Archie is way more into... Miss Grundy. Yeah. Who is a much younger (and hotter) character than in the comics, but again, this show is weird.
I straight-up guffawed with laughter multiple times - both ironic and not. Betty, Veronica, and Kevin Keller are all fun. Cheryl Blossom is fucking crazy and that actress gets points for commitment. Josie and the Pussycats show up long enough for me to hope that they'll do the songs from the JATP movie (and that any random character, when asked why they're even there, will respond "I'm here because I'm in the comic"). There's a goofy metatextual element with all the parents being played by former teen show stars (including Sideshow Luke Perry). I'll keep watching because I'm certain it's going to fly off the rails in spectacular fashion, and that will be delightful.
And, also, hoping that the Punisher is revealed to be the killer. Because fuck it, go whole hog.
