17. 'Riverdale' (CW)
You know what wasn't such a hot idea? "Archie Comics, but with an edge." So let's hear it for dingbat ideas that turn into great TV shows – because Riverdale turned out to be a gloriously absurdist high-school bitchfest, flipping the squeaky-clean malt-shop mythos on its head. Seriously, Miss Grundy boning Archie amid a flurry of Clueless-meets-The Big Sleep banter? As Veronica says, "Can't we just liberate ourselves from the tired dichotomy of jock/artist? Can't we, in this post-James Franco world, be all things at once?" Even the casting of the parents is a savvy twist on teen iconography – Skeet Ulrich is Jughead's biker dad, while Madchen Amick (the Duchess from Gossip Girl!) is Betty's mom. And the real coup, as Archie's parents: Ladies and gentlemen, Luke Perry and Molly Ringwald.
