"All" never literally means all, -1. Some people even like GW Bush.

if its simple for you, fine keep it simple....and don't mess with the midichlorians..

if you want something a little deeper, absorb the scientific aspects into the force...

if want it really complicated, then the EU fleshes that out...

why does any one version of it have to be 'wrong'?

Wrong? Well, that's a bit strong. But the midichlorians concept certainly clashes with the nebulous, inexact qualities the Force had in the OT. It's jarring to see something mystical turned into something quantifiable - or do you like to know how magic tricks are done before you see them?
