Although it has its amusing moments, in eneral the plot does not convince.

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.

I didn’t really have many expectations going into the movie (good or bad), but I actually really enjoyed it. I really liked the characters and the banter between them.

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