An irony here is that Disney was ALWAYS working on old stories. In fact their most iconic old movies are usually based on old stories that were "soft-rebooted" by them.But I'm not sure why we're listing these as attempts at 'new' franchises when they're all based on previous works
That's basically what Disney always did best. Get a basic story, nothing revolutionary and soft-reboot it to something comfy that offends almost nobody.
That's not always bad, it does have a place in our hearts, however, never expect from that company to truly promote the "new".
At its worst incarnations that company just turns plain destructive. e.g. rewriting Luke Skywalker to make no sense or remaking Lion King to something uninspired.
