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

Although it has its amusing moments, in eneral the plot does not convince.

Go in cold, and you're likely to emerge with your blood boiling. This has to be seen to be believed.

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?
