Let us not forget, Disney is a corporation. To a certain extent, we hold the 55 (and counting) full length animated movies produced by the Disney Animation Studios to a different standard than, say, the 32 (and counting) full length animated movies produced by DreamWorks Animation, or even the 16 (and counting) full length animated movies produced by Pixar, despite the fact that there really isn't much reason to, at this point. Just the fact that the brand is much older maybe should count for something, but, let's face it, just because it is so old, Snow White and the Seven Dwarfs has less in common with Zootopia than Kung Fu Panda 3 does (even when factoring out the furry aspects and the use of CGI).
We still treat many of those early animated Disney movies almost like sacred texts, despite the fact that Disney never has. Disney has always treated them like what they are; products to be sold. So, you've got annual theatrical re-releases for most of last century, a practice that only died when home video became a thing. To combat that, they introduced the "Disney Vault", which basically extended the "re-release" strategy indefinitely even with home video. Then came the direct-to-video sequels; finally, when those became a bit too damaging to the brand, the live action adaptations began. And the most recent movie to get that treatment is Jungle Book.
Whine all you like about originality and creativity, but Disney's got a business to run. This strategy is pretty much a brand-strengthening exercise, but at least part of the branding is based on "quality," so at least they're going to try and do right by the old movie (if not exactly Rupyard Kipling). And, hey, most of the older Disney movie's are based on properties that are public domain; if Disney doesn't do it, someone else will (and in fact, Warner Bros. has its own Jungle Book movie planned). And its not like Disney hasn't done this before (or, for that matter, that they were even the first movie studio to adapt The Jungle Book). If you want originality from Disney, go watch Zootopia again.
If you want to watch a good movie, well, actually, watching Zootopia again is okay, but do take some time to watch this version of The Jungle Book. It's actually really good.
