Those involved in the creation of the art can write a contract that stops it being ruined by future owners. When the Bobs sold their rights to Back to the Future they added terms to protect the brand. I know of one time where they intervened to stop a 3D conversion that Universal wanted. (Personally, I think 3D conversion can work well, e.g. Titanic, but other times it is monstrous, e.g. Star Wars Ep 1)

Copyright is a deal to encourage the creation of more information that society sees as valuable by granting limited time monopolies. If we don't all end up with the unmolested work in the end then it had no right to ever receive any copyright protections in the first place. The original creator isn't even the primary party being harmed here - they already got their paycheck out of the deal.
