I have to disagree quite strongly. The number of adaptations that are recognized as merely being good are very small. The number that are actually better than the source? I can count on one hand the number that I'm aware of.
And while film does allow you to do some things you can't with a book and vise versa, I honestly feel that that's a shield that adapters use to deflect from criticism. The best reason for a change I've ever seen was that dobby was too expensive for the Harry Potter films to animate so it was easier to have Nevil do it, which I don't even consider a very good reason.
I didn't see Dune so I can't say.
I'd consider that a failure for GoT honestly.
Wheel of Time depends on who you ask.
I'm not sure which One Piece you're talking about for sure, but the anime was made by a Japanese company, which is a whole other ballpark. I'd honestly be more excited if it was a Japanese company instead of Apple, though Apple is probably better than most other American ones for this project.
Arcane is a fair point I forgot about that one.
