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?

It is neither dumb nor smart enough to be fun, and spends way too much time with its boring human characters.

There are moments that feel comical, some horrific, and some downright inspiring but the tonal shifts hardly matter as the end results come to a film that's perfect for this time.

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