I just saw The Departed and it was as good as people say. It has particular resonance for me having known a guy growing up who was exactly like Matt Damon's character. Generally, I don't like movies with more than three well known male actors because they don't look actually like actors but just a bunch of dudes hanging out. That's fine for an Oceans 11 type movie where that's the point, but not for real movie. The Departed doesn't have this problem.
On the other hand, I don't like Jack Nicholson. I just don't think he's a good actor anymore.
