A live-action sequel to Aladdin rather than the remake we’re getting would have to include somebody trying to recreate Robin Williams version of that character, and nobody wants that.
Because we don’t need to see these movies again, but we love the characters all the same, sequels are the way to go.
Take the animated original as a given, and then come up with a live action sequel that will give us something fresh and new.
But if even just a few of these movies went the sequel route, it would at least change things up a bit and let the remakes feel a bit fresher when they did happen.
