The Rules:
--Premiered between 2010 and 2019
--30 minutes or longer
--only one film per maker
A Thought:
This list tends to be dominated by white men, which speaks to who still, in 2019 and in the advent of digital, has the resources necessary to work at feature length.
Addendum:
What the hell, let's go to 30.
