Fun premise, good actors, bad writing. This film seemed to have potential at the beginning but it quickly devolves into a trite action film. Ultimately it's very boring.

The film makes a home in your brain and the only cure is to see it again.

One of the most extraordinary films you will see this year. Take that as you want.

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