I just finished The Disposessed and found it critiqued both the capitalist and anarchist society. The people of Annares have simple happiness, but they starve and strive to keep the society alive. It’s also very explicit that it only works because they don’t uphold their anarchist ideals and coerce everyone into work through social pressure.
I think a film would work and would present a “you could have a different society, but it would never be a paradise” type idea.
