On it's own, of course it was a success. But it hasn't set a trend of successful successors anyone has pointed to so far. The model works, we know that. So logically, there should be at least a few movies in production of the same variety as Tangled for people to point to and say "Rub & Tug isn't happening and wasn't coming from the right mindset, so if you want to support trans representation, take a look at these movies and keep an eye out for them coming out."
Now that I'm thinking about it, that's a gig for a YouTube channel to keep track off. "Insert movie has issues, please check out these other movies for similar themes and better representation".
