Some Tolkien fans love Peter Jackson and will boycot if he is not the director.
Other fans have nicknamed him "Butcher" (I post on a LOTR forum sometimes), because of his apparent lack of understanding of Tolkien's world.
I personally do not like what he has done, Sauron is not an eyeball and now whenever I attempt to start a serious Rowling Universe vs. Tolkien Universe debate, I have to explain that he did have a physical form--we just never see it in the Trilogy. It is mentioned in the Appendixes that Sauron in his alias as The Necromancer took the Third Dwarf Ring from Thorin's father himself.
