Interesting. Brad Pitt seems to be a love it or hate it type.
I don't really love him or hate him. So you're wrong!!!!!
No, seriously, I think he's really good in some stuff (Fight Club, True Romance, Seven), but I also think he does a lot of pretty-boy stuff, which, admit it, if you looked like him, you would too.
But, I think for him to do Fight Club when he did, when he was at the height of his chick flick/sexiest man alive stardom, takes real guts, and I do think he's one of the ballsier actors out there.
Also, I don't know if he's since come out against or for Bush or the war or anything, but I saw an interview with him around the 2000 election and they asked who he thought won the election, and he basically said "I'm an actor, why do you care what I think about that, go interview a political expert, not an actor." I respected that a lot.
Oh, and he was on Jackass, which was really cool.
