I read that interview, and there was plenty of education with how the ranked choice voting worked, and it seemed like the issue wasn't with ranked choice voting at all.
The issue was that now that multiple candidates (~15), people weren't sure who they wanted to vote for. Since it wasn't just a "favorite" out of two people after the primaries, people needed more education on who all the candidates were. That seems like an easy fix though as long as people can visit a single website or get a brochure in the mail listing who all the candidates are.
I watched it about a month ago. I thought the story wasn't anything super new, though having no dialogue made it a bit more interesting. The visuals were really good, and I liked the world-building. Without spoiling too much for other readers, the ending was a bit weird for me, and I'm not sure if there was really a message the creators were trying to tell in the last 10-ish minutes.
