'Ringer' (The CW)

( The CW )

Premieres: Tuesday, Sept. 13, 9 p.m. ET

It's impossible to discern the excitement over "Buffy the Vampire Slayer" star Sarah Michelle Gellar's return to weekly television from the vehicle that's made it possible. Either way, "Ringer" is one of the most talked-about shows of the new season. So is the hype worth it? Let's just say that we've seen much stronger pilots. But what it lacks in its first outing, it more than makes up for with its dizzying premise, enviable cast and loads of potential. It might be a game-changer for The CW.
