10. 'Supernatural' (2005-Present)
If there's an Achilles heel for horror as a genre, it's the wafer-thin characters: Why bother crafting the next Jane Eyre if she's just gonna get chainsawed in half? But no TV series can survive if no one cares about your heroes and villains, and this CW show has taken that lesson to heart. The saga of demon-hunting brothers Sam and Dean Winchester is driven almost entirely by their emotional connection, courtesy of engaging performances by Jared Padalecki and Jensen Ackles. Yes, creator Eric Kipke's initial goal of "scar[ing] the crap out of people" is achieved on a weekly basis, but even when the stakes are outright apocalyptic and the monsters all but unstoppable, it's the ties that bind these bros that have made this show a fervently loved fan-favorite.
