In the lotr and hobbit film they have this motto that I have picked up on. All elves are smart and all dwarves are dumb. In the buku the high elves are supposed to be smart and the wood elves are supposed to be dumb. In the hobbit book when bilbo and the dwarves get captured oleh the wood elves every thing is made of leaves and wood, but in the movie there is no clear difference between the high elves and the wood elves. And in the lotr book legolas is kinda dumb and gimli is smarter but in the movie the writers switched up their personallities. maybe its just me but it agrovates me so much!
