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.

The biggest problem with this movie is it’s a little better than you think it might be, which somehow makes it worse. As in, it takes itself a bit too seriously, which makes most of the movie feel kind of dull.

The tone of this movie is interesting -- the stakes are both dramatic and high, but it's balanced with a lot of fun, tongue and cheek dialogue.

The film never slows down or bores, plunging from one harrowing sequence to the next.
