Interesting but a bit confusing.

Interesting, original screenplay, indescribable, excellent cinematography,

A mind-bending thrill ride, that leaves you constantly wondering where the story is leading you. Keen directorial choices provided a fresh movie-viewing experience.

Twisted and deranged, so overall a good movie. If you take twilight zone, shutter island, and cocoon you'll end up with this movie. Oh also add a hint of Hostel.
