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

Fun premise, good actors, bad writing. This film seemed to have potential at the beginning but it quickly devolves into a trite action film. Ultimately it's very boring.

The story, direction, characters, and writing/dialogue is akin to taking a tranquilizer shot to the neck, but everything else was so well done.

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