The Oscars is a massive political circlejerk that chooses awards based on cash and not merit. Don't be surprised Disney won. They always do.
(Off topic, someone needs to knock them down a few pegs. I, as a conservative, think they're getting to be too big of a company. That's how massive of a company they are.)
The Oscars have no actual meaning when you account for those factors. Zootopia won because it was political and because it was Disney, despite Kubo being 50x more original of a concept and having the gall to not pander to pop culture (Regina Spektor vs. forgetira). Moonlight won because black guy and "ooh introspective and social commentary!!!111!!!11!1!11!" Self Delete Squad won because it was a bigger movie, not because it was a better movie. I don't like either SS or ST:B, but Trek's costume design far surpassed the "supa-dupa edgee" look of SS.
If you still watch the Oscars, you're wasting your time. That translates to other awards ceremonies as well. You determine what's good, and if the Hollywood establishment's interests don't line up with that, then they're going to feel it at the box office and in the ratings.
