Flynn has no redeeming qualities. He just confessed to a teenager.
I do like that movie though. The mother in Tangled is actually a good way to teach kids some important lessons about abusive relationships without being super dark. She demonstrates over-defensiveness, love-bombing, gaslighting, etc.
It was a way to teach my kids about how you can lie even though every word you say is true. If you listen to the mother, pretty much everything she says is technically true, but in almost every line she has, she is being deceptive.
