Plot so thin, it passes unnoticed.

A brilliant film that helped define a genre

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."
