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.

I'll tell you why so serious

A great movie, one of the best of this year. There was a bit of confusion at one point in the plot, but nothing serious.

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