I really want to know what it was that LucasFilm saw in Rian Johnson that made them believe he could do this. He has good story ideas, sometimes(they’re kind of hit or miss). But I find his execution style to be all wrong. He’ll come up with an amazing idea, but then play it off a certain way in the film that destroys it. He’s not a great story teller that respects mythology and cultural impact. He’s more of a conventional film maker, with quirks. That’s not enough really to helm a Star Wars trilogy.
Have you even looked at the TLJ box office numbers? Just because you’re didn’t like the movie doesn’t mean his work has no appeal for others.
