This ones as old as time and as tedious as reading this article: any defect in script or acting or story quality can be resolved with the spectacular. Throw enough money and special effects into the mix, hire Shia LaBeouf to gallivant around squealingly and youve got yourself a guaranteed hit. The audience psychology behind this one is obvious: people are more easily drawn to an explosion or a fight or a shootout or a sexy time than a thoughtful conversation. Its your fault for being so basically and predictably human. You deserve all the Shia LaBeoufs you get.
