Christopher Tolkien may be an ass, but he has good reasons. He is mainly trying to protect the integrity of his fathers work; most movies destroy the true spirit of the books. He has also been harassed by LOTR fanatics most of his life he's sick of it.
I do not HATE him; without Christopher, we would have neither "The Silmarillion" or "Unfinished Tales" today. Furthermore, I can't really hate a person that I don't even know in real life. Yeah, there's a lot of things going around on the net and in the papers, but is everything true?
I don't HATE Christopher Tolkien (but I don't love him either..I just don't like him..but I don't hate him...and he's certainly not evil). I just wish he would see how happy we the fans are with the films... If it wasn't for the fans loving his father's book then we would have never heard of the name Tolkien. 🙂
