what kind of comments does he make?
Based on the two interviews I read, these are the things he said that stood out to me (in a bad way). Please note that I am not wording this verbatim. I'm just giving the gist of what he's said, and also paraphrasing.
-He said that superheroes are fine if you're a child. If you're an adult and love superheroes, then you suffer from a Peter Pan disease that the corporations made you develop.
-Superhero films are okay enough to be called popcorn movies. They can't be profound. They are ultimately about nothing.
-Superhero films are part of a right-wing conspiracy, because superheroes fight and kill to force their opinions on people that don't follow their moral code.
-Superhero films are taking over the film industry to the point where no other movies are "allowed" to be made.
Thankfully, these kind of extreme opinions don't show through in Birdman. He put his storytelling over personal opinion, which was great (and highly appreciated, since I find his opinions to be quite pompous). The movie certainly questions the authenticity of the art behind big blockbuster movies, but it mostly focuses on how these big money-makers affect the artists (like how being Birdman affected the main character). There's a social commentary on how we as a society today often consume the work being made, but we don't take the time to acknowledge the artists who made it; that we all see the masks, but not the people/actors/artists behind those masks.
Along with all of this, the movie also hilariously shows Edward Norton (one of those "artistic, screw the establishment" actors) being a huge, egocentric jerk. He's especially a jerk to Michael Keaton, since he views himself as more of an "artist."
