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.

Watch something else. There are very few redeeming qualities to this 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 story, amazing characters, superb action, enthralling cinematography. Yes, this is something I am glad I spent money on.
