Basically a pointless list. Most characters would have as strong a claim as another.
Locks for top 10:
Tyrion Lannister
Walter White
Don Draper
Omar Little
Other characters with a good shot, but which I don't necessarily endorse:
Peggy Olsen (Mad Men - they'll need a strong female character and it'll be Peggy or Leslie)
Louis C.K. (Louis - probably the strongest sitcom character in this time?)
Nucky Thompson (Boardwalk Empire - No Boardwalk fan likes Nucky more than Richard Harrow, but he'll end up higher because the list makes no sense)
Leslie Knope (Parks and Rec - see Peggy above)
Hannah Horvath (Girls - because Lena Dunham is a voice of a generation)
Also.. Finn the Human from Adventure Time?
GOB from Arrested Development should rank fairly highly too, as would Larry David from Curb Your Enthusiasm.
Oh and Liz Lemon!
