This movie is a fantastic series of twists and turns. One of the few I've seen recently where I genuinely couldn't predict what would happen next the majority of the time. Very decent quality too - pretty good actors, cinematography, etc. And the effects aren't terrible.

Some later parts in the film might be a little unsatisfying (no spoilers here) but even those parts are thought-provoking and interesting so I'm unbothered. When it's funny it's very funny, and when it's dramatic you can feel the suspense. Overall a very decent movie much better than the cheap lighthearted film I figured I was getting into.
