He's too creative and artistic to be written off as a hack.
I totally understand why people bash his movies. He rehashes classic horror movies, keeps casting his wife, roots in favor of sociopaths and is trashy.
BUT...
He's a competent director and creative as freaking hell. I've only seen his movies once, but if I never see them again, I'll remember the set pieces and characters. You can hate his movies all you want, but the sets, sense of atmosphere, artistry and cinematography are definitely better than most.
