Bad Acting and worse Bad Screenplay

It's fun, it's light, [but] it has a hard time when its tries to get heavy.

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.
