The reason that everyone's boosting him right now is because that's who they want to "be the next Spike Lee". But that's ridiculous because there already is a Spike Lee.
I don't hate on him because he's improving. Now, I'm assuming you haven't seen his movies. But judging from what he's done, he does have some potential. I doubt that he'd ever make an "Oscar-worthy" film but I think he could make some decent films.
But I do see your point on the writing, though. My whole point is that, in the context of what he's done, DLG is a good improvement.
