White House Down is an action movie, nothing else. You'll laugh at the easy quips, be amazed by the action and the explosions, but don't be attached to reality, because it barely flirts with it. The story line is simple and just this side of brainless. The scenario is well paced and gets your heart racing, but has no novelty. You'll cheer the heroes, but there's no depth to any characters. It's better than Olympus Has Fallen, but barely.
Good mindless entertainment, nothing more.
