Good start, but then it gets ruined

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.
