TV's underrated stars of 2012: Zap2it's Year in Review

Ty Olsson, 'Supernatural'

You know him as: Benny, a vampire who became Dean's brother-in-arms after a year in Purgatory together.

Why we like him: Though the character is a vampire, Olsson plays Benny as a smooth, Southern romantic -- which makes for a nice change on a show where optimism generally leads to death. Most importantly, Benny has brought out a new, emotionally accessible side of Dean (Jensen Ackles), a welcome change after rejecting any signs of vulnerability for several seasons. We've got high hopes for Benny's storyline this season.

Where else you've seen him: Olsson is best known for his work on "Battlestar Galactica," though he also appeared in the second season of "Supernatural" as a different vampire, named Eli.
