The development of Anakin Skywalker and the Jedi led to what would prove to be a contentious addition on George Lucas’s part- the introduction of midi-chlorians as the means through which living beings felt the Force. Some fans felt that this scientific approach diminished the more spiritual aspects of the Force, but actually, this was necessary. Training Anakin was supposed to be against the wishes of the Jedi, but if Qui-Gon Jinn, and later Obi-Wan Kenobi, was to train him despite that, he would need to have more than mere intuition to force the Council to accept this. The introduction of midi-chlorians presented indisputable evidence that Anakin was truly a unique example of Force potential. Lucas didn’t add them because he wanted to explain the Force. He added them because he needed something that would force the Council to act despite their instincts that Anakin was dangerous, that his raw potential was so great that without training, he would likely become a threat.
