I like Tim Medows, and liked when he did the bit on SNL. Of course he does much of the same stuff from the SNL stuff in the movie. However, like one of the cast says "You get to see TLM outside the radio studio." So, you get to know him more/better, etc. It's worth watching, and I'm sure I'll watch it again sooner or later. If you like the other SNL movies that have come out, you'll like this one.
Chris Rock needs to make a movie where he's that militant black guy. Can't remember his name though. Something X of course. That is, as long as he can get over the fact that he's not white. . .
His last comedy thing I saw on HBO really turned me off of Chris though. WAAAAAYYYYYY to much 'fuck whitey' in it. TRYING to be funny with it, but was sounding more bitter than funny. Fuck whitey is funny, but not when it's whinning. Then it's just annoying.
