I’d say the fact that leftist socialist or communist movements keep decaying into authoritarian dictatorships is a pretty big weakness of communism, actually. I think Western capitalist countries are not perfect by any means, but they’re winning the quality of life game, even of poor people.
It’s a bigger problem that barely has to do with the specific shows or movies. Marvel Studios has mostly been coasting since Endgame. It also didn’t prioritize female led properties, so they’re all coming out in this coasting period. This means they might be on average not as good. It’s not directly because they’re female led, but it is sort of indirectly because of that.
