Without remakes, Disney will have Marvel, SW (will wane after TROS), and its animated films. Unless Disney can come up with SUCCESSFUL new live action materials, that's all they have.
As far as John Favreau's choices in giving the animals less emotion, I've read and researched the "uncanny valley". Not a hard concept to understand, but miscalculated. Basically, for those who don't know about it, it says that the closer something is to being human-like, the more it creeps people out. It's as if when you make something more and more realistic looking, people think it's cooler and cooler until you hit a point where they are repulsed and scared of it. That point is known as the "uncanny valley".
Narnia '05 didn't hit it but the animals showed great emotion. TJB was very realistic and had decent emotion. Netflix's "Mowgli" had poor digital work by today's standards but WAY too much emotion. People were repulsed by it. With TLK, Favreau went further with the realism but was afraid of showing too much emotion for the fear of scarring kids (and adults) for making the animals too realistic. Problem is, TJB was just fine and people actually WANT emotion for TLK because the animated was so expressive. Thus, I think it backfired on Favreau for not pushing it in TLK. At least as far as critics have gone it backfired. We'll see what audiences think. I'm a little worried because I think people are much more attached to TLK than Aladdin.
