But then I realized that Star Wars is a combination of science fiction and fantasy, with your wizards flying in starships and whatnot. So, the magic of the Force having scientific roots is very fitting, and it explains why everybody in the Star Warsuniverse doesn't use the Force, because they can't.

This, for me, is part of the reason why I dislike the midichlorians. Part of the magic for a lot of people (especially kids) when the originals came out was that anybody could tap into this mystical field and become a superhero - even a humble farmboy. Then Lucas said, "Uh, well no. Uhh... you have to have superior genes. Sorry!" and basically just ruined that mysticism. It's like putting a price tag on the force. It's supposed to transcend that sort of thing.
