The film makes a home in your brain and the only cure is to see it again.

Good films always raise compelling questions, whether the format is fiction or documentary fact.

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."

It is neither dumb nor smart enough to be fun, and spends way too much time with its boring human characters.
