Yes given his clear talent with heady sci-fi with Arrival.
So he needed blade runner? He was already an established director before he joined
And Arrival isn't a clear indication that he could make a great character centric SW film?
My point is that needing is irrelevant. If he wants to make a SW film, it could be both entirely original and captivating.
Wanting to keep him away makes little sense at all, unless you just personally hate SW. He makes too much sense to not eventually join that universe.
