Editor’s note: It sure would have been swell for Neon to have distributed the movie they’re pushing for Academy Award consideration in the US in its original language… but they didn’t. The only version the US gets to see is an English language dub. It’s not like fans of animation have strong opinions about subs vs dubs. No biggie.
