i too am not amused by Steve Carell...
that may be because every character he plays, is the same character. same with fallon.
I've seen little that Fallon has done, but he doesn't strike me as amusing. Agree that Carell isn't funny, but he doesn't strike me as rude or self-absorbed. Others who are not funny - Will Farrell, Jack Black, Queen Latifah, John C Reilly, and pretty much most of everybody else right now who's making a living in professional comedy. It's sad, really.
