I’d mostly agree, but the sequence where Keaton flies is sublime and almost saves the picture.
I never got to see that part of Birdman, having walked (rushed) out after the first hour. I did not like it at all. Every scene felt as though it were the very first scene of the movie. I’ve not experienced that from any other film or director.
I’m sure the director had his reasons for the endless pastiche of jagged scenes and jangled dialog. I bonded with no one in the film, not the main character, and certainly not his daughter. Everyone was equally unpleasant, exposing their own brands of personal pain. This was a film many actors praised, because it bespoke of the inner panic that wraps around the thrill of getting an acting job. A big No Thank You from me.
“Almost” is the operative word. :)
Basically, you have to have seen the series to enjoy the movie. I think it’s based on the cartoon.
