I read your "manifesto" and most of the replies and I think your position is somewhat extreme. You are, of course, entitled to your opinion and you are completely free to state your views but don't you think you're going a bit too far on this one? I mean, "Mists of Avalon" were based on a book, that I, for one, haven't read. I was somewhat surprised with the movie and the story itself, but, in the end, it's just a story. A story about people raised with different beliefs than yours, a story about an imaginary world filled with people we know since forever. I think it's a good contribution for the myth of Camelot, King Arthur, Lancelot, Gwenhwyfar... It would be very boring to think of Merlin just as he was in the Disney movie "The Sword in the Stone".
I think "The Mists of Avalon" (the movie, since I haven't read the book) deserves all the respect. It has great performances, great music, lovely costumes, beautiful scenary, in short, it's an eyeful! If you feel ofended by the story, then don't watch it, but you shouldn't "label" it as pornography because it's far from being that.
Don't be so strict on movies and books or you'll end up just reading Louisa May Alcott and watching Jane Austen movies!
