I could live without the wizard duel also. Mmmm, I like the love scene! I think Sauruman looking into the Palantir more, getting all weird would be better than the "way of pain!" The cave troll scene could have taken a few cuts, That early part with Legolas on it's back reminded me of those old "dyno-rama" movies (Jason and the Argonauts). I didn't really need that "Lurtz" fellow, but I must admit to getting a kick out of that scene where the Urak Hai are painting themselves up with the white hands. cool!
