Oscar 2015 Logic Error for Best Film Editing

Hello!

Is it just me or does anyone else see the logic error behind giving Birdman both Film of the Year and Best Cinematography but not a Best Film Editing award for its continuous One Shot post production edit of the ENTIRE film? I know the film won other awards during the oscar but if you are going to recognize a film for something visual, as in the cinematography department then clearly it should be backed up by the outstanding editing of the film itself which separates it from the other films nominated.
