What a freaking movie. So many twists and turns. Absolutely intense from start to finish.

Fun premise, good actors, bad writing. This film seemed to have potential at the beginning but it quickly devolves into a trite action film. Ultimately it's very boring.

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."

If you like to be scared, if you like to laugh, and if you like to learn a thing or two at the movies, this absolutely cannot be missed.
