Use my picks for your Oscar pools and contests, and if you enter the ones I already entered, and you win, send me a postcard, okay?
Caveat: There are a lot I haven't seen (for instance, for Best Picture, I only saw 2 of the nominees. Although Crash was one of them, the others weren't elimimated because I didn't see them like Bill Murray did on "Weekend Update" on Saturday Night Live. Until recently, I thought Brokeback Mountain would win. It was Roger Ebert's reasoning, as well as Entertainment Weekly's Oscar pick issue that report that Brokeback Mountain mania has peaked, and Crash may be picking up steam.) As alluded to earlier, my predictions are based on my cinematic viewing, Roger Ebert's picks, Entertainment Weekly's picks, things I've read elsewhere, and ultimately my own gut feelings. Given how many short films and documentaries that make it to Indiana, that's about all I've got to go on. And the "smaller" categories such as Costume Design, I'm one of those yay-hoos who complained about Ghandi winning it for "putting a bunch of sheets on people".
As Kim Metzger has written in the past when he gave his Oscar predictions, this isn't as exact a science as making sports predictions. It's not as much guessing who is better or who will win, but how a group of people will vote. And you don't find out the final score, just who won. Price Waterhouse isn't going to say by how much the winner won by, or how many votes the runners-up got.
But in my defense, I have won an Oscar contest before, the year Marisa Tomei won. And I will fight anyone who wants to debate that win anytime. As with anything on the Internets, it's IMHO, YMMV, GD&R.
