Such a frustrating disappointment

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.

A movie that not only functions as a solid scarefest but a razor-sharp satire.
