Saw it a couple of weeks ago and I was really looking forward to it. A bit too much perhaps since I didn't really llike the outcome of the film. The concept itself is great but they way it turned out wasn't that great. Samuel L. Jackson was great and even Hayden Christensen wasn't too shabby, but God, the ending was horrible. At least, that's how I thought about it. I don't think there could be a more obvious clue to making a sequel than that. I was so hoping for that battle between Jackson and Christensen, but nooooooooooo, of course they're keeping that for the sequel. Including that, I found the film too short as well.
I haven't seen it... I guess I'm going to be renting it and not buying it after seeing this thread though x_X
