It was OK. I don't see why everyone loves it so much. It wasn't very smart or deep or well-directed.

Just intense enough to provide a much-needed diversion, just lightweight enough to make you forget about it soon after it’s over. It’s not exactly “good,” per se, but it does what it sets out to do in terms of putting us on edge, which makes it … successful?

One of the best movies of the year! Incredible from the beginning to the end.

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