I would've been happy with a three-disc for each LOTR as well. I can't say I've watched any of the bonus features on the first two EE sets. But I love the extended versions of the movies. The EE footage in Two Towers made that movie my fave of the bunch.

As for Mohicans, that is one of my fave films, too. I don't have it on DVD yet, though. I'll hold off. I've held off this long. Another one I'm waiting for an SE of is the original Batman. Burton's gotta have something up his sleeve. And hopefully Warner will push for it come time for the theatrical release of Batman Begins.
