When all is said and done, quite possibly the most overrated American director to emerge from the 2010s.
Superficially, this cries out for rebuttal. I immediately thought of Andrew Bujalski because just with Computer Chess and Support the Girls he has those same fundamental problems except for the score. Also, like DuVernay he was around before the 2010s but gained more attention in this decade. If I didn't have to limit myself to a time frame, I would say THE overrated director of the 2010s is Zack Snyder.

...or better yet, don't.
Now that I got the silly stuff out... bold claim and I fully support it. Not to entirely blame her, but the marketing for Wrinkle in Time referred to her as "Visionary Director" while none of the footage supported it. The end result was closer to Aeon Flux than Denis Villeneuve.
I do like the way she makes her case in 13th and from what I heard about When They See Us, maybe she's better with documentaries which doesn't ask for a strong cinematic aesthetic.
