I feel like it established some pretty common elements in sci-fi (eg, the violence channel) and was the first time I saw on film concepts from Huxley’s Brave New World.

It’s a low budget movie and I think it’s ok to be a single note film. But that note was really unique on 1971 and seems rote because it’s sort of baked into the “consumerist hedonist dystopia” that’s very common now.

Much of the world building of SW was done by the fans, Lucas really knew how to build a brand even back then.

Definitely agree, but I feel it's worth watching for the cinematography / set design alone.
