Lack of good storyline.

Instead, you get a movie that's enjoyable enough, but leaves you feeling like it could have been much, much more.

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

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.
