It has potential, but the structure of the movie is pretty weak.

It has a deep message, lot of symbolism, metaphors, but I think it fails to deliver. And the structure of the film feels weak, is like all over the place, at first seemed to be some thriller with a big build-up, then, it goes all surreal, then again thriller, and so on.
I liked the premise, but overall it was poorly executed.
Also the cheesy death scenes were... well, that, cheesy. (Only the first mass suicide was done well, IMHO)

Anyways, good movie.
