So I just got back from watching Live Free or Die Hard, which was a spectacular movie. Spectacularly bad, that is. Although highly entertaining. Among other things, the movie features Bruce Willis hanging from every conceivable item (a walkway, an F-35 plane, the open door of a car balanced precariously in what appears to be an elevator shaft), jumping out of a car at the last moment, to send it up a pillar with such precision as to collide with and take out a helicopter, surfing on the wing of the aforesaid F-35 as it's about to crash, and in a spectacular wheelie with an 18-wheeler, which Mr. Willis gets out of, against all known laws of physics, by turning the steering wheel in the direction that will actually disbalance him more. (At the end of this scene, I wanted to jump up and cheer, and throw loose change at the screen!) And, of course, there were some scenes that were lifted straight from other movies (the elevator shaft scene carries shades of one of the Jurassic Park movies, for instance).

And as we stood around rehashing and laughing hysterically at some scenes, the conversation rolled around to the worst movies we've ever seen. Immediate contenders for the rank of world's worst movie were:
a. Independence Day (Best line: "Today will be known as the independence day of the whole world.")
b. Dante's Peak
c. King Solomon's Mines
d. Matrix Revolutions
e. Commando
f. Air Force One (Best line: "Get off my plane!")

What thoughts, people? If I wanted to watch some really, really terrible movies, what would you recommend?
