Simple and well acted, it has tension enough to knot the stomach.

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

It's the kind of movie you'll want to see a second time with someone who hasn't seen it yet, to remember what it was like to watch it for the first time.

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