Great movie. Loved it from beginning to the end.

This is an instant classic! Perfect summer thrill ride.

Fun, smart, with genuinely interesting things to say about human nature. Every twist is earned and has a great payoff, every shock is measured and used well, with gore being used only when it is most effective. The movie naturally includes a lot of characterization and backstory that is completely essential to understanding the universe and the development of the story.

Great movie! Kept me on my toes throughout the whole film!!
