Die Hard 4.0 stars Bruce Willis in a story where he single-handedly foils a cyber terrorists plot. It's not surprising that he's a one man army and the film is actually believable at first. A group of terrorists hacks into the US's cyber-infrastructure and takes control over them, causing havoc through disabling utilities, crashing the financial sector etc. The first hour was good and intense because it slowly reveals the objective of the villains, and how John McClane is caught up in all this. However, it slowly starts to degrade into another typical action movie with exaggerated explosions and belief-defying stunts. It really throws reality out the window at the end where John McClane survives some crazy situations such as a jet fighter exploding from a few feet away. You start to feel the weight of the film from the one hour mark as it starts to slow down. However, the film was still enjoyable and the story is passable.
