Been thinking about this. Currently have four movies in mind, and they're all Ms:
mother!
Melancholia
The Master
Mad Max: Fury Road
Roughly in that order, I think. Each time I've watched mother! (three times) it's grown in my estimation. It's one of the most perfect films I've seen, and every single minute is an intense delight. Melancholia is so glorious though—a very close second.
Anyone have some thoughts on this decade?
