Ugh. They're all turds, IMHO. It's ridiculous that they think the show can't carry on without Charlie Sheen. It doesn't give him a sense of burden, it just inflates his ego even more. His character has never seemed like a huge part of the show to me, anyway. Even if they don't think it can carry on - I don't see why they don't at least give it a shot. It's insulting to a group of people to say "We don't think we can make the show work without a crackhead."
Charlie Sheen is just fracking nuts all the way around. There's something wrong when all your other family, who is in show business as well, manage to keep themselves off the crack and out of the tabloids and you don't. He's become like Lohan and the rest - you just start to tune it out because its expected.
My mom will still watch the show, but I can't stand it any longer - because of Sheen AND the rest of the powers that be who have decided that the entire show is dependent upon Sheen.
