I liked the aspect of the force being more democratic and mysterious and its choosing a neophyte no one to restore the balance. I liked that Last Jedi basically made the whole mutant inherited bloodline thing, irrelevant. Only for Rise to make Rey a Palpatine and undo the idea of Star Wars going back to the style of a the original where Luke was a no one, who had the courage to leave Tatooine and confront the Empire. Originally Luke was a brave kid who went on an adventure he wasn’t the son of a super-villain/mutant with the most mitochondrial DNA or midichlorians whatsits in existence to some prophecy. Its undermines the force and free will. Its junk.
The thing is George never said the Force was exclusive to bloodlines. I think what he says about is just the opposite from how both J.J. and Rian took it to mean.
"A lot of people get confused about the Force. They see it as some special thing that you can find and pick up and put it on your head and suddenly you have the Force. Whereas it’s always been designed so that every [living] being has the Force.
The amount of Force, which is like talent or intelligence, is different in every person. Some of it is inherited, but it’s no more than a talent. It’s not something you can acquire – it’s something you can learn to use. I have the power to lift that cup off the table using the Force, but I can’t do it unless I have been trained to do it."
And with the Whills. They tie into the idea of free will and destiny:
“The Whills are a microscopic, single-celled lifeform like amoeba, fungi, and bacteria. There’s something like 100.000 times more Whills than there are Midi-Chlorians, and there are about 10.000 times more Midi-Chlorians than there are human cells. The only microscopic entities that can go into the human cells are the Midi-Chlorians. They are born in the cells. The Midi-Chlorians provide the energy for human cells to split and create life. The Whills are single-celled animals that feed on the Force. The more of the Force there is, the better off they are. So they have a very intense symbiotic relationship with the Midi-Chlorians and the Midi-Chlorians effectively work for the Whills. It is estimated that we have 100 trillion microbes in our body and we are made up of about 90% bacteria and 10% human cells. So who is in service to whom?”
The reason we follow the Skywalker family isn’t because they’re more important than others who can also use the Force but because the saga was about Anakin and his family. Anakin and his family just had a greater destiny akin to God in a general sense. Some have greater destinies than others and it’s also your choice on if we want to act on it or ignore the call to something greater. Fate has a way a stopping in where it’s needed.
