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.

Go in cold, and you're likely to emerge with your blood boiling. This has to be seen to be believed.

I think this is a new genre that they're all sort of working their way through it and haven't got all the kinks worked out yet but it's a genre that works for me.
