Although it has its amusing moments, in eneral the plot does not convince.

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.

The film's masterful storytelling did its job. The message was clear. No need to overdo.

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