It was OK. I don't see why everyone loves it so much. It wasn't very smart or deep or well-directed.

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's funny, it's tense, it features two great performances from two actors and the director expertly creates a web of odd tension where you actually don't know what is happening for the majority of the run time.

There's a more than satisfactory amount of boom-boom in the movie's trim running time.
