I generally agree with you, with one caveat. When a visual version of a book does not treat its source material with respect, and it’s a source material I love, then I’m okay with trying again. Some could make the case for HP falling into this category, I guess. But I’m thinking more along the lines of Disney’s Black Cauldron, an unholy mashup of the first two books of a series I adore, that not only disrespected its source material but straight up changed basically all of it. I would love to see a faithful adaptation some day but I suspect I never will, so I’ll keep rereading it every ten years or so instead.

Remaking things that were originally visual media, though? Or remaking anything in the same format it appeared in originally? I tend to agree with you. Extend the story instead if you must; skip the rehash. And we’ve seen the trap that these mega-franchises get into when they can’t escape what they see as the gravitational pull of the original.
