The performances transcend the film's tropes, grounding it in characters that feel more complete than this subgenre often produces.

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."

There are moments that feel comical, some horrific, and some downright inspiring but the tonal shifts hardly matter as the end results come to a film that's perfect for this time.

The film may be flawed, but its message is not.
