I mean, if you really wanted to do a dark version Archie, tell it from the perspective of someone in Riverdale who becomes increasingly weirded out that his odd, uncharismatic guy is somehow working his way through the entire town and surrounding area like he was in some kind of dating sim or gross harem anime or something. Or the romantic comedy version of that one Black Mirror Star Trek parody episode.
You could make it a meta commentary on those kinds of genres, particularly the creepy wish fulfillment aspect of it, but have the slowly building dread of someone realising that they’re trapped in a town that’s always slightly out of date, where no one ages, and where sooner or later everyone WILL date Archie makes for a much more scary, interesting story than “Betty’s got the serial killer gene, whoooooa!“ or “that bomb Veronica’s dad planted gave us superpowers, I guess?“.
Just saying, if you’re going to deconstruct it, there are more effective ways to do it than making a show that seems to be a parody in of itself of teenage dramas (ALL teenage dramas, regardless of genre). Ed Brubaker in his Criminal series, for example, had the storyline Last of the Innocent, which was a noir crime story that was basically a deconstruction of the stereotypical Archie story, where several years into his marriage with Not!Veronica, Fake!Archie regrets his choice and plots to murder her to be with his other highschool girlfriend Not!Betty.
Should be clear that the Archie analogue is very much the bad guy in the story, and it’s effective a tale of him ruining several people’s lives in his selfish quest to get back the life he thinks he deserves (albeit one where he has the Veronica expy’s money for himself, but married to the “nicer” of his two girlfriends instead).
What I’m saying is, if you’re going to do it, there are several ways it can be done in multiple genres. It helps if the story you’re telling is actually trying to SAY something though, either about the original story, its genre or the time it was created, otherwise you just get a potentially mean-spirited, grimdark story that exists JUST to be a shallow parody.
