This movie sucked + is a ripoff - see ALTERED instead...
This movie was pathetic. The twist is so obvious, if you can't figure it out by the end then I fail to see how you can function in the real world.
This is a suspense film with no suspense, a thriller than offers no thrills, a horror movie that isn't scary.
The premise is nice; a cult spouting end of times propaganda. Only, this movie would have been better if it wasn't A COMPLETE RIPOFF OF THE MOVIE called "The Rapture." (http://www.imdb.com/title/tt0102757/).
How is it a ripoff? Well, in that movie, Mimi Rogers warns people that the end of days isn't really approaching. Turns out she was right. Then as a twist, the "rapture" does occur - it really is the end of the world after all. This movie plays out exactly the same, instead of christian propaganda, it's about a cult of evil scientist/mathematicians who later turns out to be true. Same story.
AVOID. Altered is a far superior piece of work, and please don't blame the budget; the story sucks no matter how much money he had at his disposal. Budgets don't fix script problems.
