The Phil Dunphy character on Modern Family. I just hate the awkward comedy thing.
Everybody loves the show, and maybe the other characters are good, but this guy ruins it for me.
I LOVE Phil. And Ty Burrell plays the character perfectly.
I'd have to vote for (or against) Christopher on Gilmore Girls. Please, go away Chris, and this time stay away.
Dishonorable mention goes to all of Amy's family on Everybody Loves Raymond. The stereotype of the uber-religious family missed the mark IMO. Her brother Peter was especially bad as played by Chris Eliot. (Paul Reubens was AWESOME as Peter in the episode where he was introduced.)
