Lilo & Stitch is a great example of a story that has no villains. It has antagonists, sure, but most of them are well-meaning. The worst person in the film is that little shit Myrtle, but she’s not in the film that much anyway.
Since this post is getting traction I want to clarify how not-villainous the antagonists are:
- The Grand Councilwoman is literally just responding to what she sees as a threat to the galaxy and is extremely reasonable.
- Gantu is much the same. He’s a bit overzealous, yes, but he thinks he’s saving the galaxy from stitch.
- Cobra Bubbles is literally just doing his job, he’s obviously not happy about it but he is doing what he feels is best for Lilo. And much like the Councilwoman, he is extremely reasonable.
- Myrtle is, again, just a little shit. She’s a schoolyard bully and is truly small potatoes.
- Jumba calls himself an “evil scientist,” but literally nothing supports that. His only onscreen crime is creating a bunch of Pokémon that have powers that will mildly inconvenience people and can be persuaded to be nice over the course of 22 - 90 minutes, to say nothing of himself seeing as he decides to change his ways at the softest bit of persuasion.
- Pleakley is literally just gay.
The "villain" of Lilo and Stitch is, rather directly, societies and social systems that write people off and do not provide support and care.
It is obvious to the audience -- and deliberately presented this way by the film -- that it is better for Lilo to stay with her sister, even if her sister is a bit of a mess and not financially stable. Mr. Bubbles is not evil. He is there because he wants what's best for Lilo, and he is not unreasonable to think that the sister without a job who leaves the stove on and whose house nearly burned down two days later is not it. The solution is not to "defeat" Mr. Bubbles; the solution would be for society to help Nani succeed, rather than watch as she fails.
Similarly, no one provided any help to Stitch when he was created and discovered. They wrote him off as an abomination, something too dangerous to be destroyed. They weren't evil, and it wasn't unreasonable to think that the experiment created to be an agent of destruction would be better off scrapped. But what would have happened if they had at least tried?
Lilo and Stitch are two characters who were caught in systems that were cold, uncaring, and unsupportive, even if the people in them were not evil and were, in fact, just doing their best.
It's a movie about people who have been written off finding one another and building a found family where they can get and give the support and care they didn't get from the people with authority and I love it so much.
