SERIOUSLY. This is what the crap Hollywood still puts out?

The performances transcend the film's tropes, grounding it in characters that feel more complete than this subgenre often produces.

I am only giving this movie a 1 for the great cast, though I can't imagine what any of them were thinking. This movie was horrible

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."
