Too much of everything

Simple and well acted, it has tension enough to knot the stomach.

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?

There is definitely an excellent idea hidden in the background of the film. Unfortunately, it's difficult to find it.
