I thought the LotR films were brilliant, and I'm interested in hearing what you thought was disgraceful about them.
Maybe disgraceful is a little far. There's no sense in beating up on Peter Jackson too badly. It was an impossible task. And going into it, adapting the LOTR, of all things, was like scheduling a cage match with a T-Rex. My main complaint was, at the end of it, it didn't stick. It was just another action/fantasy movie and forgettable.
This probably has more to do with not meeting the mood and imagery I'd created for myself while reading the books a half dozen times from say, 12-16. But as far as particulars... A lot of the casting choices really bothered me. Particularly Legolas, and Sam. Actually, the entire Elven portion of it felt too polished. Too much lens flair.
The way the dialogue was cut down left the story feeling formalized. The parts that stuck with me all these years were the gluttonous food descriptions after weeks of being on the run. Of the sheer terror, laying in the ditch outside the shire when they first encounter the nazgul. Of Tom Bombadil, who they completely cut out. Of Mithril being completely OTHERWORLDLY, which I don't know how you'd portray properly. Of just how goddamn fast Shadowfax was. Of the one ring taking everything out of him. (think Trainspotting detox meets The Passion dragging the cross.)
I was very disappointed in the sexualizing of Galadriel. In the book, they were in awe of her. No lust. That came as a real shock and seemed very Hollywoodized.
It's just not suited for live action. There's too much to fall short on when you're trying to make THE definitive visual adaptation. No matter how short your actors are, and how good your cgi is, this is always going to be closer to the spirit of the books. imo.
Here's gollum from the animated film btw. I love the part where he starts paddling with his arm. http://www.youtube.com/v/ZRz47UvOKXA&hl=en&fs=1
