Purely Joyful Movie!

What a freaking movie. So many twists and turns. Absolutely intense from start to finish.

The film makes a home in your brain and the only cure is to see it again.

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."
