Wasn't the last I watched but birdman, cause it got a oscar or somethin
The single takes were amazing, especially the shots taking you around the windy halls/stairways of the theater. Also dug the satire of superhero hollywood. Also dug the livng shit outta Keaton.
Doesn't score higher though cause it's hard for me to empathize with the quest to be critically anointed/recognized as a Serious Artist. Which is what it seemed to me to be about.
