In my day job I work with IP getting adapted into other formats quite a bit, so I feel like I've gone from the kind of person who always thought "The author knows best, dammit! Adapt everything exactly like the source or gtfo!" to being the kind of person who respects the talented people often involved in the adaptation process and hates working with really precious creators.
I liked the Netflix adaptation of Heartstopper better than the original comic. The pacing was better and it just generally felt more cohesive because webcomics can be a bit "first drafty" and having the benefit of looking at a series like that overall and reworking it can be a good thing. I also believe that the insistence of E L James that the second two movies in the Fifty Shades series be as close to her books as possible- to the point she put her husband in the director's chair instead of the original director who tried to turn the books into something more coherent and to have the protagonist more agency and personality- was a bad thing!
There are obviously points at which something becomes a "no-no" and where I'd use creator influence to try to veto things in an adaptation. Like I dunno, if the script handled Jules' autism in a problematic way and infantlised them and they wanted to cast a neutotypical actor, I'd be a bit like "umm... I don't like this, and I don't think the fans of my series will like this."
But if like... They said "hey, this Sarin character, can we rename her? Her name is a nerve gas." My response would be "Sure, okay. I named her as a teenager, and it was just some pleasing sounding syllables to me, and I stuck with it in the reboot because... that kind of became her name to me, but if it's too much of an issue, let's brainstorm a new name for her!"
There are lots of scenes I've had to cut from the comic to make it a viable length to create solo, so maybe I'd even be able to work some of those back in! That'd be cool!
Generally, I'd want to be involved in the production, but not as a person who keeps telling the production team not to change my masterpiece, but as somebody dedicated to making a really great animated series that people can enjoy without reading the original comic, and taking on board the input of others. (Well, I hope it'd be an animated series because live action involves... either an absurd budget or terrible effects and also....WIGS .) Let's be real, I'm an okay story-planner, but I'd be the first to admit I'm not the best at writing dialogue that sounds anything like how humans talk, so a more experienced writer would probably do a better job than I did in a lot of places!
