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 an exhilarating, distressing, funny and profound film, with one of the more memorable film scores in years,

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.

Strong acting helps the film overcome an uncertain premise and create characters that hold our attention absolutely.
