Probably the most fun I've had watching a modern action movie in... shit I don't know how long. Richard Donner directs the film into a frenzy of 70's era stunts and plot twists, which give the movie a feeling closer to 3 Days of The Condor than Die Hard. Bruce Willis is pretty great as an over-the-hill can barely stand up beer gutted shit bag of a hero, and Mos Def teeters on being annoying, but manages to stay endearing.
Look. It's not Shakespeare, or shit, even Scorsese but it's a breath of fresh air and worth the money.
