I'm going to be really strict here and not count some favorites of mine who emerged in the late 90s like Nuri Bilge Ceylan, Jafar Panahi, Lynne Ramsay, Harmony Korine, Shane Meadows etc. I'm sticking strictly to millennials.

My top three:
1. Asghar Farhadi (most definitely first place, actually a contender for my all-time favorite director)
2. Cristian Mungiu
3. Calvin Reeder

Other great or at least highly promising ones: Andrei Zvyagintsev, J. C. Chandor, Nina Paley, Sylvain Chomet, Andrew Bujalski, Laszlo Nemes, Radu Jude, Joachim Trier, Marjane Satrapi, Greg McLean, Clio Barnard, Oren Moverman...
