Fun nonsense, full of proper real explosions and stunt work, and Willis's and Jackson's bickering, buddy chemistry that makes it seem lovably old school. Plus, Jeremy Irons has a charisma that explains why people would gladly die for him. If in any doubt to its quality, compare to the same year's "Bad Boys".
This is both crazy and off-the-wall in all the right ways. Sure it´s loud and stupid but it really delivers action and suspense by the minute which is the whole point. The chemistry between Willis and Jackson also makes the movie very entertaining.
My personal favourite of the Die Hard series, this injects new life into it, another interesting villain played by a fantastic British actor, and one of the few films that brings together fantastic cinematic partnership Bruce Willis and Samuel L. Jackson.
