This list was HARD to make. It was not an easy task for me. I'm not even sure if it's 100% accurate, but it's pretty close nonetheless. No one from Battlestar Galactica is on this list, but if it was top ensembles it would obviously be near the very top of the list!

Homer Simpson (The Simpsons)
Jack Bristow (Alias)

I know you said specify the show, but do we really need to specify for Buffy The Vampire Slayer and Angel? I mean, the two are practically the same show. If that is a problem, just put 'em both down for Angel.
