Assuming it hasn't changed in the last couple of years, IMHO (and my wife's) the queue for Dr. Doom is the best I ever seen. There are a series of "cartoons" shown which give you info on the ride, and the safety spiel, but they are done in the style of Eastern-European propaganda films. They're not just clever - some are almost subversive (i.e. "We will develop a peace-keeping weapon so powerful it will destroy all our enemies). My wife and and I have actually just stood in the line watching these, waving people past us.
The castle for Dueling Dragons is also pretty cool ...
