... fucking loved this season. he tackles alot of serious issues about age, success, etc. there's an episode where he is in contention for the new david letterman for late night show. he's up against seinfeld, and chris rock comes along and spreads rumours about it, etc. - brilliant. don't know if there's any truth behind the whole thing, but at the end louis ck gives it to letterman. if you haven't seen it, you should watch season 3, who said comedians couldn't act, fuck he killed it.
