If you've had a bad week at work, and want to watch some bad guys getting their heads blown off, while the US Secret Service crash around incompetently, while the terrorists are imbued with preternatural powers of planning and infiltration, this is for you.
I love it. It ws silly, gory, gratuious, lacked any sense of reality - totally.
But it was fun at the end of a week of stress - pure escapism.
Don't take it seriously. I'm not sure that it takes itself seriously. And it doens't require ANY thinking.
