After watching What We Do in the Shadows, Orlok's Transylvanian accent just reminded me of Nandor so much that it made every single one of his lines sound funny rather than threatening. It also sort of neutered the jump scares to the point where they were so expected that they almost seemed campy. I did enjoy it, and I've watched it twice already.
Also, by far the weirdest sex scenes I've ever seen in a movie, including Irreversible.
