Lack of good storyline.

Although it has its amusing moments, in eneral the plot does not convince.

Clever and entertaining enough to recommend even to members of the 1%

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?
