"When Hermey the Elf doesn’t want to make toys like the other elves, and expresses that he wants to study the fine art of teeth instead, he becomes an outcast like the titular Rudolph," says Lauren Kranc. "But the film teaches us to celebrate differences—at its close, Rudolph saves Christmas with his special nose, realizing that being different is really a gift, and Hermey opens a dental office in the elf village. It’s truly the only film in history that celebrates a passionate dentist joyously getting to do what he loves."
