3. Elf
Although Elf isn't technically about a dysfunctional family, Buddy's relationship with his biological father is pretty dysfunctional at first. And it's not as though we can go without including this delightful, Christmas cheer-filled film on this list. So grab some popcorn and get ready to follow the adventures of Buddy the Elf as he travels from the North Pole to the Big Apple to find his dear old dad. Yes, for the millionth time: "SAAAAAANTA!"
