Good concept, poorly executed.

I really wanted to like this movie. I feel terribly cynical trashing it, and that's why I'm giving it a middling 5. Actually, I'm giving it a 5 because there were some superb performances.

Great story, amazing characters, superb action, enthralling cinematography. Yes, this is something I am glad I spent money on.

Yes, absolutely, there is fun to be had, as well as many, many things to go boom, all amid an atmospheric urban jungle.
