Plot so thin, it passes unnoticed.

It's not great by any means, but it's a pretty good movie that didn't leave me filled with regret for investing time in it.

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?

The film may be flawed, but its message is not.
