So for instance the new Star Wars series drew the original cast back but... they didn't do jack. In fact they were portrayed, largely, as failures. I didn't appreciate that. Game of Thrones tried to 'subvert expectations' and decimated the story it was building for years. The Wheel of Time... ugh don't get me started.
This makes me curious. For me and my perspective. I have enjoyed a lot of the Star Wars live action that most fans seem to dislike or despise. I enjoyed Solo, I enjoyed Book of Boba Fett. One could look at Solo and think, that's not his character, his time as an Imperial Fleet was more than that, its where he learned flight patterns enough to fake out the shuttle approach while going to teddy bear moon.
I tend to look at it in the classical since. Its tales from a very long time ago. All the works aren't going to agree and down the line, we'll pick and choose the parts we like and disregard the ones we don't. Any old mythology is all one has to look at. Greek mythology wasn't written by one author, nor was Arthurian legend. In fact, there is still works being created about them today. A lot of folks enjoy Percy Jackson, no one is saying, that is not Perseus how could they do that character injustice. Some of the recent Arthurian movies have taken the revisionist western point of view, it was a gritty time and he was a far more gritty bastard than the French writers painted him out to be (noble, chivalrous).
The curious part is how is it that in recent years/decades/etc if a derivative work comes out it has to be true to one source? Do we go back to like Cervantes being possessive of Don Quixote such that when other authors borrowed the character, he had to write book two for the express purpose of killing the character off to end any further adventures of Don Quixote? Is it just me being old and enjoying these other takes? In comics, a new telling of Peter Parker getting his powers and morals in new and interesting ways is what comic fans like. How is it most of us deviate from this if a TV show or movie goes 'off the rails' and doesn't stay true to the source?
Not to argue it, just curious what makes it 'true' to the characters vs off the rails and why live action seems to be the line in the sand of things being too far off the mark.
