I would like DC to make a revamped version of the Justice League, but this time as a prequel to Young Justice using the adult justice league characters. (Batman, superman, wonder woman etc).
Marvel wise, an animated young avengers show with Spiderman and some others would be cool.
Stormlight Archives, in a similar style as Netflix Castlevania.
I don’t think they could ever pull it off as live action because of spren everywhere, the sheer scale (we’re taking lord of the rings scale battles on the regular), and of course the literal fucking grass being alien almost everywhere (which is kind of relevant to the plot)
But animation has no issues with that.
