I disagree. All that's canonically known, is that there is some connection between midi-chlorians and the Force and that a high midi-chlorian count is an indication that a being is Force-sensitive. No canonical information says that midi-chlorians create the Force, are the Force or make a Jedi strong. It just indicates potential to use the Force.Susan Arendt said:Because it turns being a Jedi from a personal journey of self-discovery, discipline, and spirituality and turns it into an accident of birth. A strong Jedi is no longer someone with the stronger focus or will, just someone with more bugs in his blood. In short, it cheapens the mythology.
If you grew up on the first trilogy, you're more likely to hate midicholorians with a passion.
So it's not like the Force is explained all of a sudden, midi-chlorians just provide a way to detect (amongst others) Force-sensitive beings. Plus, don't forget about the difference between a Force-sensitive being and an actual Force-user. That personal journey of self-discovery, discipline and spirituality is still needed for a Jedi to be an actual good Jedi.
You can have an amazingly high midi-chlorian count, but all that that says is "He could use the Force really well" and nothing more. It doesn't guarantee that that person becomes a good Jedi (there's more to being a Jedi than using the Force, way more) or even becomes a Jedi at all. Just look at Anakin "My life sucks so much" Skywalker. Lots o' midi-chlorians, crappy Jedi.
Thus, tl;dr, I see no reason why someone who grew up with the original trilogy would have to hate midi-chlorians with a passion. They're not what you think they are.
