I was totally surprised at how great this film.You could feel your paranoia rise as the film went on and as you gradually learned the details of the real situation.

In truth, there is barely enough story here to make a film.

A film with more than the usual spoiler issues. Talking about it in any detail feels akin to handing you a gift-wrapped present and saying, "I hope you like it -- It's a thriller about a diabolical secret experiment."

Great example of an old-fashioned, pure-at-heart escapist event movie that doesn't pretend to be anything that it's not and has boat loads of fun being its own ludicrous self.
