I can honestly say that I have never seen an episode of that show. Am I missing something good?
You would not like it. It's morally corrupt. It's also very, very funny at times. There are reruns on Fox at 7 and 7:30pm on weeknights.
The show is about a drug and sex addict who's an entertainer, buying prostitutes and acting like it's perfectly normal. The character's name is Charlie on the show. In other words, if Sheen leaves the show, the show is over because it IS about him.
