I noticed the two comments mentioned, but wasn’t able to link it to Neitsche the way the author did. What I thought the film was saying was that the struggle to keep everyone equal was hurting society as a whole – sort of like the Rush lyric, “And the trees were all kept equal by hatchet, axe, and saw.”
I didn’t see the “elevate the supers” angle that Neitsche spoke of, but rather a rebellion against the notion that we should keep from offending those that are not particularly bright or talented by making a point not to encourage those who are. To me, putting gifted people on a pedestal is another issue entirely.
Anyway, do check it out; it’s an interesting read.
