Good start, but then it gets ruined

It's hard to see any effort in the film. There's no comedy to speak of, no real drama and, worst of all.

Let me be very fair here, this is not the best movie in my opinion. But, this movie is fun, it has purpose and is very enjoyable to watch.

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