[Galadriel]

There are quite a few pet peeves:

1) Frodo, Pippin and Merry, and Gimli are entirely out of character. Frodo is portrayed as a weak pansy, Pippin and Merry are utter morons, and Gimli is just the useless dwarf who is there only to entertain. Oh, even Elrond did not act like himself.
2)Glorfindel and Gildor do not appear. I will KILL Jackson some day.
3)Aragorn is hyped up too much. He stole Legolas' role in Lothlorien AND his line about having no fear when they were about to enter the paths of the dead.
4)No Tom Bombadil. Need I say more?
5)Frodo actually tells Sam to get lost. That was one part where I nearly tore my hair out.
6)Shelob's lair was useless. That was the best chapter in the book, and practically NOTHING happens in the movie.
7)Legolas serves no purpose in the movies. He saves everyone's life in the books (The Great River).
8)The bit about Frodo singing and dancing on the table and then falling off is removed!
9)Gandalf is actually beaten by the Witch-King. What. The. Heck.
10)Faramir is a DIFFERENT person in the movies.
Um, I could go on and on...
