Yeah I agree with that. I like the realistic animals used in the park. If by some miracle we ever got a Jungle Book ride I'd prefer it based on the live action movie. It's also why as much as I'd love one I'd rather not get a ride based on Lion King.
I don't think Jungle Book makes sense in the park narrative. While there could be debate, I don't believe the movies (definitely not the book) are set in the modern day. Asia is a modern day experience. It would be odd to place something from a century ago in a land about today. Furthermore, all iterations of the Jungle Book have animals that are either not accurately placed in their habitat, displaying nonnatural behaviors, or are incorrectly portrayed. For example, numerous animals were portrayed in the most recent movie as significantly larger than the real world creature. The old animated movie featured a species of Apes nonnative to India. Disney's Animal Kingdom prides itself on accurate portrayals of Animal behaviors and features, and would immediately be at odds with that mission. Perhaps most egregiously, the new Jungle Book Film featured an animal that is extinct in a feature role all without acknowledging the break. While there is a place for imaginary or extinct animals at Disney's Animal Kingdom, it must be in a properly supported area like Dinoland or BK.
It's also worth noting that Jungle Book is not a product of Asian Cultures. While there are certainly traces of the culture in the book, it was written by a European from a European perspective. The follow ups have also been created by Americans from an America perspective. If there must be a dark ride narrative, I think it would be far more fascinating to have a South Asian story told in way that enriches the land and park.
This also ignores the fact that the ride would have to take place in the first person. A retelling of the adventure wouldn't cut it. It would have to be your Adventure in the setting of the Jungle Book, at which point you have to wonder why even bothering with IP.
Jungle Book isn't necessary or even appropriate at Disney's Animal Kingdom. Think Original.
Edit: Hah, I didn't even mention that the book and park have different themes and messages. That's another problem...
