Charlie seemed to be pretty positive that no one could replace him, or at least not do a good a job.  After it has been anounced that Ashton Kutcher will replace him, he doesn't seem to keen on the idea.

"Ashton Kutcher is a sweetheart and a brilliant comedic performer. Oh wait, so am I!!" the actor griped Friday. "Enjoy the show America, Enjoy seeing 2.0 in the demo every Monday, WB. Enjoy planet Chuck, Ashton. There is no air, laughter, loyalty, or love there."

Charlie's talking about Chuck Lorre, Two and a Half's creator and the root of quite a few of Charlie's rants as well as the reason that Charlie parted with the show.

"I can't replace Charlie Sheen, but I'm going to work my ass off to entertain the hell out of people!" Kutcher, 33, said in a statement.

Ashton got the role after Hugh Grant dropped out of the cast last minute.  How much will the gig pay? $650,000 to $750,000 is the word on the street.
