The Virgin Birth angle was disgusting.
And changing The Force from a metaphysical manisfestation and into alien parasites was also junk.
I agree, those two items were completely unnecessary.
Perhaps the “virgin” birth thing could have been explained better if there was some exposition or scenes of Palpatine’s master, who is thought to have been able to utilize the force to create or extend life.
The only way I could see that working is after the opening crawl you have a scene where Palpatine witness his master doing that to Shmi Skywalker right before he betrays his master. If that was set on Tatooine it would sort of tie into why that planet figures frequently in galactic events even though its a backwater planet.
