Just got done with this. I thought this was a great movie. Really crazy movie. I thought that the pace wasn't balanced but it was right on after watching it. The acting was all Michael Douglass, Sean penn is in this but he doesnt' do much.
I think the storyline pushes the line of believability, but the storyline is amazing. A good keep you guessing kind of flick.
Anyway I would recommend watching it, it isn't old enough to be a classic, but it's not recent at all =).
