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

It isn't all that great, actually. Really cheesy and very predicable of how certain scenes are gonna turn play out. However, I guess that's the charm of it all, because I would consider this one of my guilty pleasures.

it is the rare 'crazy' movie that actually has something to say.

The film's masterful storytelling did its job. The message was clear. No need to overdo.
