How did Rian Johnson got so much power at Disney?

Coming from the awful Looper and a few Breaking Bad episodes this guy has no resume as to say it is a good choice to take your billion dollar franchise, it would be like having a 2 years experience engineer in charge of Microsoft or Apple or a newly graduate medic in charge of the Mayo Clinic out of nowhere, even if they were geniuses you lack the experience to have something that big that you did not create.

He is either a real life Jedi (or sith lord) with mind control powers or someone on the higher ranks just liked his script and diced to go with it, this sounds like a case of "lets get a unexperienced CHEAP guy to inject something new to our franchise".

Even worse, he is given total control over the following movies, a complete trilogy until now, I am sure there were a ton of people with more experience and good fresh ideas to be given as much power as this person.
