Pretty darn good -- I think.

Rating: 9/10 (25 October 2007)

Well, I just watched this last night (actually ending @ 3AM) so it would be nice if I can edit this comment later, but I think I'm giving this a 9 (or better). I think the main thing I want to say about it is that it's a film that I want to watch again and maybe more than twice. I found the way it was cut in the early part of the film was kinda "preview-like" in that the images shown jumped around like you see in a preview. I frankly was quite confused for a lot of it because I had trouble telling Matt Damon and Leonardo DiCaprio apart during a lot of those scenes. They were dressed a lot alike during much of it, yada yada yada.
Now, admittedly this is largely a function of my own stupidity (or ignorance) but I still found it hard to follow the significance of what was happening. That would have been more annoying if I had been seeing this during its run in the theaters, but it's not a problem now that it's on DVD. In fact, it makes it a good thing because I can go back and catch what I missed the first time thru.
I suspect the effect was intended, but that's just a guess. There seemed to be a general theme of "confusing the viewer" throughout the film. Makes for good repeated viewing. Also, mixing up the two characters enhances the main theme of the movie as it "blends" them to the point of making them somewhat "indistinguishable." As Jack's character points out: when you're facing the business end of a gun, "what's the difference?" Billy and Colin weren't that much different after all, were they? Each was performing the same function for his respective "side." The film reminded me a LOT of Goodfellas, one of my personal favorites. It was most definitely and obviously a Scorsese film as his stamp is all over it. It's a fine film and worthy of praise. Very powerful and had me engaged throughout. And eager for a 2nd viewing. I guess that speaks highly of it.
Leonardo's performance was superb. So was Jack's -- but we've come to expect that, and he was largely just Jack being Jack. Matt Damon was fine but I think I'm not all that much of a fan; and I think Leonardo's performance just overpowered Damon's. Maybe it's just me. I'm not a Leonardo fan but I might be on my way to becoming one. He could be the new Johnny Depp -- if he isn't already.
Excellent film. Highly recommended. But be forewarned, it's violent.
