Midichlorians. One of the most controversial aspects of the PT. The one that seems to have been more easily fixed and it mostly involves removing dialogue. However what if there was a way to include the midichlorians as a conservative aspect of the Jedi order?

That is to say, instead of Qui-gon having faith in Anakin because of his midicount, Mace should demand a count (in my interpretations they are related to the force but having lots of them could very well mean nothing). Dubbing would be requiered for this, but I believe the Jedis being conservative is one of the better devices in that trilogy and needs reinforcement.
