Just as a note: I'm currently running E1: Death's Reach, which I consider to be one of the best adventures I've run. The plot line is suitably epic, and (once I upgraded the monster damage to the new maths) the monsters are interesting, if the players still do well in most of the battles, well that's how I want D&D to be. 
My basic belief with epic adventures is that they can't have foes from the "real world". You're looking at outerplanar threats. E1 is really good about this: the "grunt" monsters are shards of an ancient primordial... which then features massively in the plot of the E1-3 adventures.
Malcolm Hulke remarked upon hearing that the third Doctor (Jon Pertwee) stories would all be set on Earth that it left the production team with only two types of story: Alien Invasion or Mad Scientist. You've sort of got that dilemma for Epic adventures. Does Sauron count as a Mad Scientist?
Cheers!
