You know what's the absolute worst? When you're totally in love with a TV show, but there's one actor who nearly ruins everything.
Maybe you dreaded all of Season 8 of The Office because you hated Catherine Tate as Nellie. It wasn't completely her fault, since her character was so unlikable, but maybe you think another actor would have brought a little more charm or humor to the role.
Perhaps you always hated that Kevin McHale played Artie in Glee when the role could have gone to an equally talented actor with a disability instead.
Or maybe you adored everything about 30 Rock, but as the seasons progressed, you kept thinking that all of Tracy Morgan’s lines weren’t delivered as great as they could have been.
Whoever it is, we wanna know! Tell us which TV actor was terribly cast — and don't forget to explain why! — in the comments below. Your response could be featured in an upcoming BuzzFeed Community post!
