I've only seen The Case Against 8 and Life Itself. I am dying to see the others,
which are Virunga, Citizenfour, Last Days in Vietnam, Keep on Keepin' On and Tales of the Grim Sleep.
There's maybe a different atmosphere than say, the Directors, there's definitely a greater sense of togetherness. There are a lot of experienced working men in here, like steve James and Nick Broomfield or women like Laura Poitras and Rory Kennedy, but there's also this Australian drummer called Alan Hicks, who directed his first documentary and end up being grabbed by Havery Weinstein.
This is always a must, for me.
