Good concept, poorly executed.

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

While it is a pity that the story wasn't told with more visual finesse, this is trivial compared to our real-world problems. It takes a good movie to put that into perspective.

One of the film's great tricks is that, for a time, you think it will go down a rabbit hole of unrealistic glorification.
