Foreign language films don't deserve to be in the Oscars. Last time I checked, this was America. The Oscars are in America. Land of the english speakers.
I actually think it would be better if they blocked any non-English movie from nomination to any Oscars except foreign language oscar. Why? Because Academy Award is a ceremony for the American film industry so nothing more natural to block everything else from being nominated. The Japanese Academy Prize (see https://en.wikipedia.org/wiki/Japan_Academy_Film_Prize) for instance only nominate Japanese films. It is not xenophobia to do what they do with the Japanese Academy Prize: it is only recognition of what it actually IS. They should do just like the Japanese awards and make the award to be officially about the US film industry, also they should include "American" in the name, so it is "American Academy Award".
I really don't like this thing they have where they pretend it is not a ceremony for the American film industry so instead of just officially blocking non-English films they nominate 99% of the time English language movies and from time to time a non-English language movie shows up (yes, it is that degree of biased proportion). Why do that? It is hypocritical.
