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.

Excellent and certainly provocative... If nothing else, the film is a real conversation starter.

It's the kind of movie you'll want to see a second time with someone who hasn't seen it yet, to remember what it was like to watch it for the first time.

One of the best movies of the year! Incredible from the beginning to the end.
