Hi! Newbie here:
On the Potter front, I'd say, well:
Eh...in a property that's supposed to have an element of dark realism to it I don't think that would look very good.
Rowling explained she turned people who wanted to "cartoon-ify" Potter down, and I think she was right to do that.
Maybe another Wizarding World property could be animated, but in a series that skews older and darker relative to other four quadrant franchises today, most from Disney, I don't think animation would be very good for the franchise.
It would cheapen it, lessen the emotional and dramatic elements, which would be really bad for the story, and I've gotta say, the marketing crisis that would arise from people thinking dark and violent films about death were intended for little kids because they had an animated counterpart would be a nightmare.
People have already turned Harry into some sort of absurdly geeky, childish cartoon figure who always wears striped scarves and looks like he's 7, and that's totally incongruent to how he is in the story. How he even looks. The whole POINT of the coming of age genre and the "Wizarding World" aesthetic. I shudder to think what the media and the cultural elitists would try to paint Harry Potter as if it were literally cartoonified.
In a Bildungsroman, a long one, animation would cheapen the experience and I don't think there's a market for that, and I know Rowling wouldn't like that.
DC is a superhero franchise, it has more younger skewing marketing and merchandising on average and already has cartoon property in DC Super hero girls and tons of animated series and films, including a Lego movie tie in. That's going to and should happen in animation before anything happens with The Wizarding World.
If Wizarding World's last film is anything to go by, it's that the predominant fan base of the brand has been 15-30 year old females for a while. 65% of the audience for Beasts was 25+! And Grace Randolph, YouTube star, made some very good observations: it seems parents are rather wary of the Potter property when it comes to young kids, and many consider it to dark and heavy and scary. In a brand like D.C., Marvel, or Star Wars, which have much bigger elements of their brand aiming at appealing to little boys, it might work. In a franchise like Wizarding World, I don't think there's ANY money there. At least not anymore. Too literary and cerebral for that. Methinks.
