My homage point was completely wrong, but I do stand by everything else I said. Comparing la la land to nolan's filmography is like comparing shakespeare in love to cameron's filmography.
Also, jake how can I explain fewer directors thing? This might get wierd. Ofcourse, a person will make a movie with his own style.
But I think spielberg and cameron are part of a group of directors with fewer members than a group with roman polanski, tarantino, scorsese, sofia coppola. Groups are by whose work will be more remembered. And I think chazelle will be in the later group while nolan in the first group.
