If he wasn't trying so hard to be Faulkner, his work wouldn't be such a chore to read. His prose is beautiful, but the styling is a gimmick that serves no purpose and gets annoying after awhile. If he only did it with two or three books, I'd be okay with it. But it's his style.
He's trying to turn the western (genre fic) into literature and it just doesn't work. He should be having fun with the material, but he's too focused on trying to win the Pulitzer.
He makes violence boring.
