It's the pity, actually: LOTR prooved you could make good* films out of fantasy books and lure lots of people into the movie theatres. And instead of giving all the good books a chance, they ruin it with films like these.

*Good in terms of moviemaking. Some will never like to see the book of their heart on the screen, and every film could be more perfect. But in terms of movie standards, the LOTR series was really good.
