Pretty good movie overall. First half was nothing special but it got better as it went along.

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

The movie's neither hopeful in contrived ways, nor hopeless in different contrived ways. Somehow it manages to be wonderful

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.
