It’s not bad or unwatchable but despite the amplitude of the spectacle, the end result is underwhelming.

The tone of this movie is interesting -- the stakes are both dramatic and high, but it's balanced with a lot of fun, tongue and cheek dialogue.

There's a more than satisfactory amount of boom-boom in the movie's trim running time.

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?
