Lack of good storyline.

It's fun, it's light, [but] it has a hard time when its tries to get heavy.

It’s an especially fun movie from a director and cast who are clearly having a good time allowing themselves to let loose.

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?
