I dunno about vampire dentists, but when I saw Van Helsing it was apparent from the werewolves' ears that they had been cropped and taped at some point, like a Doberman's in North America. Canine ears are not naturally that thin and upright. And I was sitting in the theatre distracted by the thought, "what kind of weird supernatural vet *crops a werewolf's ears?*"

I may not have been enthralled by the movie...
