You asked what Disney sees in him. They see a man who makes movies people want to see. If you can’t understand how this translates to Disney wanting to hire him to make movies, I don’t know what else to say.
“They see a man who makes movies people want to see”…before the man who made movies people want to see finished his movie, a movie that ended up dividing half the fanbase in a similar fashion to the prequels. They judged him too soon. Big mistake.
Here’s what really happened: Disney assumed the audience was going to love this movie, but they turned out wrong. A good portion of the audience, does not. I don’t think they understand who the fanbase is and what they want. They assume they do, but they really don’t.
If they were interested in continuing the Star Wars legacy/lore for story’s sake, they would’ve made George Lucas’ trilogy. But they didn’t, they’re rehashing old stories that have worked in the past. They’re only interested in “continuing” the lore for money’s sake.
