I think the problem is certain nerds who think they own these things. Luke can never make a mistake and grow as a human. If you change the art style of something I vaguely remember you're personally offending me. You have no stake in this as a consumer. Actual talented people are trying to expand on this while earning money for the corporations who own these things and that's a tricky parameter to work under. You don't own these characters and if you actually gave a shit about them you'd welcome any attempt by creators to expose them to a wider audience. But you don't. You just want the exact same thing farted out for eternity because it's how you remember it.
Except if it's something completely different it's not what you give a shit about anymore. It's a gross amalgamation of skimmed names and plot. It makes people NOT want to see/know more about "that thing" you like. Whether it's Thundercats or whatever. I love Merry Melodies and Bugs Bunny Cartoons, but does that mean I'm going to support shudder Loonatics Unleashed? No. Because it's something different entirely. It's about the same as most books and the movies made "from" them. Like that one His Dark Materials movie... you'd welcome any attempt by creators to expose them to a wider audience.
