We already know there's bias, and we already know the winner isn't always the one that deserves it. It's not just men and women categories - foreign films, animated films being the most noticable victims after gender. This is true for any award ceremony, sometimes it's more obvious that it's a PR stunt or a popularity contest more than actual recognition of the value of somebody's work. And no, the bias does not get addressed, even when we know it's there. At some point, a lot of viewers just assume that the ones that didn't win didn't deserve it, and the show moves on, because no one cares enough.
