I'm probably alone on this, but I think he's steadily improving with each film, very slowly becoming one of the more interesting genre directors currently working. From the retrograde Death Line knock-off of Creep, to the playful satire of Severance, the Shyamalan/Nolan-lite twists of Triangle, right-up to the "Grindhouse Bergman" of Black Death [possibly his first truly 'great' film], he's overcome the more irritating shortcomings of other contemporary horror filmmakers, such as Roth, West, Marshall, Mclean, etc, and produced that rare thing: contemporary horror movies that are about more than just homage and appropriation, but actually approach serious ideas from a semi-serious perspective.
