I have a friend who's a critic and gets me in to previews for free, so I've seen a few of these. I really liked "Venus," and "Last King of Scotland" is great. It should have been nominated for Best Picture instead of "Babel," which I thought was a pretentious mess. Other than critics, I've yet to find anyone I know who's seen that movie and admits to liking it. If I were voting for Best Picture among the actual nominees, I'd give it to "Little Miss Sunshine." Even after many decades of filmmaking, Academy voters still haven't figured out that it's much harder to make a really good comedy than to make a depressing, pretentious drama. Remember the famous last words of a great English actor: "Dying is easy...comedy is hard."
BTW, the Gore movie is a big slab of crap. Further proof that the Best Documentary category has been degenerated by Michael Moore into nothing but the "Most Popular Piece of Ridiculous Leftwing Propaganda" award.
