Tear Jerker: Babe
The two moments mentioned at Moment Of Heartwarming. Even soulless abominations from beyond the stars find the room gets a bit dusty during those parts.
Every Thanksgiving the VHS copy of Babe gets put in into the VCR and the family gathers around to watch. By the time we are all told, "That'll do pig" we are all crying because who doesn't want or need to be told that in this moment they are all they need to be.
The opening where the pigs are take to the abattoir and one of them is Babe's mother. It's very depressing for a family film.
"I want my mom." Just the way Babe says it is just heartbreaking.
Rex's backstory: It's revealed in the film that sheep consider dogs to be on the same level as wolves, that is brutal, savage predators that terrorize and kill sheep - dogs and wolves are related species wise, and a sheepdog's herding techniques are based off how wolves hunt down large animals. One night, Rex finds himself and his flock trapped in a flash flood, and tries to herd them to safety. The sheep didn't realize he was trying to save them, and thought he was trying to kill them instead. Rex, thinking the sheep hopelessly stupid and panicked, likely never actually spoke to them to let them know he was trying to help. He just used his herding techniques, which panicked them further and ultimately trapped them and Rex together, surrounded by the rising waters. Rather than stupidity on the part of the sheep, the whole ordeal fell down to Poor Communication Kills. Rex stayed with the sheep to the end, but it cost the sheep their lives; they all drowned. It cost Rex his hearing and his future as a champion herding dog.
Maa's death. That day, Babe finally learned why sheep referred to dogs as wolves, in the worst possible way, and joins in the flock's haunting cries mourning her passing.
Hoggett sounds so disappointed in Babe after that, thinking that he had killed Maa. He was visibly relieved to be proven wrong in time.
When Fly has to give up her puppies. And the night after, Babe comes up to a visibly despondent Fly, and says exactly the right thing:
Babe: Fly... Can I call you Mom?
The scene where the Hoggetts' granddaughter starts crying because she didn't get the dollhouse from TV. Not a Tear Jerker for her, the little bitch, but for Farmer Hoggett. He looks so sad after all the work he put into the house.
As awesome as it may appear to look, Rex and Fly fighting each other is shocking. Two mates devoted to each other are literally fighting fang and claw over what's best for Babe (Fly) and injured pride (Rex). And when Rex bites Mr. Hoggett's hand, you can see the shock on his face as well as Rex whining when he sees what he did. He, the one who always preached about everyone having their place, had just bitten the Boss. Little wonder he had a Heroic BSOD afterward.
Babe: Pig in the City
The scene with Flealick chasing a car is almost too much for any person to take. When Ferdinand says, "You're just a little pig in the big city. What can you do? What can anyone do?" and Babe and the monkey turn away to follow Flealick.
