I want a trilogy as good as The Dark Knight Trilogy out of this. Touching on all the big points of his career, even if 'only' thematically. Do something big and bold with it. Beginning, middle, end. NOT perpetually maintaining a status quo. Just give me that... THEN you can do your big "Everything goes forever" shared universe thing, WB.
Also, were this to go beyond a trilogy... The word would be SAGA. The Man of Steel Saga. The Saga of Superman? Something like that.
