Good story, Not enough for a whole film

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."

The film's masterful storytelling did its job. The message was clear. No need to overdo.

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