The author pretty obviously didn’t actually see the movie. There’s only one man in charge of the “Citadel”, and the place is run as a personality cult. He (the man running the Citadel) fetishizes living forever, so he maintains a harem for perpetuating himself. Women who age out of the harem are used to produce milk presumably because it symbolizes life.
I saw the movie this past weekend. My son teenage son HAD to see it. I figured it was a bonding experience for my son and I. It was very weak on plot and basically one long chase scene. I found it hard to believe it was directed by the same guy that made the first three. Those movies actually had a plot. This was just a vehicle for special effects. My son loved the movie(16 year old). I thought it was horrible.
I did not really pick up on the pro homo message. Just the fact that all men are bad and women are good. What I did not understand is if the women dominated society by the chicks on bikes was so great, why did their lush Greenland(or whatever they called it)turn into a marshy wasteland with those things walking on stilts? Again no plot.
