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.

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

The thing I enjoyed most about the film is the fact that it doesn't shy away from being a super-sized-cliche;

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