What a gross oversimplification of Nolan's filmography. That's like saying The Social Network is a fantastic Fincher film, and then dismissing Se7en, Fight Club, TGWTDT, etc.
Same with Tarantino. Pulp Fiction is Awesome, but forget Reservoir Dogs, Kill Bill, Basterds, Django.
Even without TDK, Nolan still has Batman Begins, The Dark Knight Rises, Insomnia, Prestige, Following, Inception AND Memento. That alone is a list that most directors DREAM of having on their resume.
