In terms of television programming, the last few years have been quite good for genre fans. There's The Walking Dead, of course, and the more demented American Horror Story. But there's one show that's been delighting lovers of monsters, witches, and other antagonistic grotesqueries since way back in 2005: The CW's Supernatural.

Slightly below the radar, Supernatural has been the most consistent genre show on TV, powered by the pitch-perfect chemistry between leads Jensen Ackles and Jared Padalecki, as demon-slaying brothers Sam and Dean Winchester. It's also wonderfully creative, with a never-ending surplus of inhuman villains often rendered by impressive visual effects and padded with rich, fascinating mythologies.

We know what you're thinking—a show on The CW starring a couple of pretty boy pin-up types can't be anything more than something your little sister would watch. Give Supernatural a chance and you'll discover that it's one of TV's best-kept secrets.
