It's entirely possible that sending the audience out feeling lousy was intentional

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."

This movie feels like it was made purely to piss off people who want good shows

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