I thought this worked on multiple levels. It’s an emotionally affecting human drama, an interesting procedural thriller, and a really tense horror film. They all come together really well to make you feel a wider range of emotions, sometimes simultaneously.

Jessica Chastain and Eddie Redmayne are predictably great in it. Chastain is really empathetic and believable, while Redmayne is appropriately creepy. He is genuinely likable for the first half, and it’s really unsettling how that affability turns to menace while the performance itself hardly ever changes. Even by the end, I still almost felt bad for him.

And the story itself is both interesting and horrifying. I was pretty interested in the procedural aspect of things, and while true stories like this can often seem exaggerated, this one feels really authentic, and I can totally believe this type of tragedy and corruption would happen.

It’s tough to sit through, but if you’re up for it, I think it delivers a very sad, scary, effective story.
