There's a whole lot of "TV show" in the TV show "Riverdale." Roberto Aguirre-Sacasa's small screen Archie Comics adaptation -- an inspiredly chaotic queer work that's as cheerfully absurd as it is painfully earnest when it wants to be -- burns through storylines like there's no tomorrow. It's how, in the end, the show is able to indulge in subplots involving everything from illegal teen convict fight clubs to diabolical sorcerers from alternate realities to the tickle porn industry. (That last one is very real and even features "The Last of Us" actor Spencer Lord.) The same goes for the genres it dabbles in, though there are two in particular that "Riverdale" consistently returns to throughout its run: horror and musicals.

Perhaps it's not surprising, then, that "Riverdale" birthed a pair of spin-offs in the forms of the horror-flavored "Chilling Adventures of Sabrina" and the wholesome showbiz fantasy of "Katy Keene.
