With a convoluted storyline that is hard to follow and not very interesting, we were disappointed in this movie. Had really been looking forward to it, but the final product just didn't hold up. Cinematography is very dark and the fight scenes are shot in a very unusual jerky/slo-mo style that is, again, hard to follow. The dialogue is very mumbly, making it impossible to catch some of the "funny" banter between the two main characters. Often sounds like RDJr. has a mouth full of marbles. Overall, my opinion is "see it" or "don't", its not a big deal.
I'm a big JD fan and looked forward to this movie. I found it very boring. If not for JD, we would have walked half way through. Too long, too slow, no plot and a very weird "home movie video" look used in some scenes that made the whole movie feel cheap.
