One thing: In the hands of a good writer, the mediclorians thing could be a good idea.
The world of the original trilogy is of a fallen society, which is why everything is gritty, and in that world the force is regarded as a superstition.
In the elevated, enlightened civilization of the prequels, the world is shiny and new and the force is a science they fully understand.
The problems are that a) he never explores any part of that or its impact, making it a random throwaway line and b) twenty years, the childhood of Luke Skywalker, is not enough time for that to happen.
Like, Chewbacca isn’t gonna look at Obi-wan as some weirdo for going on about the force, because he used to know Yoda.
Similarly, most of the people in A New Hope used to live in a time when people who used the force were plentiful.
Anakin was a random slave kid on a distant planet and he knew all about the reputation of the jedi.
Yet the dude on the Death Star is like, “The Force?
That’s not really a thing.”
