Well my survey of Alejandro González Iñárritu’s directorial oeuvre stalled out around the halfway point. That would be a more impressive statement if his filmography up to this point had not been solely four films. I just ran out of time to watch Babel and Biutiful before González Iñárritu’s newest film, Birdman or (The Unexpected Virtue of Ignorance), was released, but from what I have seen, I am (perhaps prematurely) prepared to declare him a pretentious filmmaker with a very strong eye for the technical aspect of cinema. Birdman has finally roosted in the cultural consciousness, and it is time to determine whether the film represents the hatching of a new era for the auteur; a “molting,” if you will.
