Self-important, over-dramatic, uninspired.

This is one of the few movies I've ever seen where the whole audience broke into spontaneous, loud applause a third of the way in.

The acting is good, and the firecracker script has some excellent ideas.

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?
