Certainly there are a lot of little inconsistencies with characters that could be ironed out with a refresh of the story. There can also be proper foreshadowing with stuff like the Triwizard Tournament and proper incorporation of the wizard world within the muggle one earlier in the series.
But, when you really dive into the worldbuilding, you keep coming back to a few fundamental basic 'truths' about how magic works and how these wizard societies evolved that precludes a "modern" interpretation to them. The Wizards essentially being slave owners, hell the entire house elf conundrum, really, adds a MASSIVE racial element depending on how you cast certain key players. It's already there a bit, but you can side walk it enough for kids and keep it light when it isn't a black Malfoy with a slave or black Hermione petitioning, largely unsuccessfully, to free them. Even calling the group SPEW, funny enough on paper, is kinda atrocious if it's applied to an allegory of the transatlantic slave trade. Not to mention the gold managing goblins, already a loaded visual depiction, becomes worse when examined more closely and in context with modern events.
Some of this is on JKR as I think she, consciously or subconsciously, employed a lot of racial stereotypes in her work, but also it's just the clash of British culture she's from versus the larger world. On the one hand that very 'britishishness' is a major appeal to the IP, but i's also a problematic component when oriented towards adults with more critical thinking capability. The later books and films veered into that territory, and I fear how the show will drag that stuff forward into the beginning and then flagellate itself trying to work it all in.
