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?

This is one of the best movies I’ve seen in a very long time. You have to go and see this on the big screen.

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