How sad is this?

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.

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.
