Star Wars vs Star Trek

[OB1]

Not everyone in the SW universe is force-sensitive, and that was established in the very first movie. Luke had that potential, Han did not. The only force users in the entire OT were Luke, Obi-Wan, Yoda, Vader, and Palps. The whole midichlorians thing just spelled it out for people. It didn't make the Force any less mystical, except for those that really didn't get what they were (like DJ).

One of the main messages of Star Wars is about the choices people make when they have power. Your potential may not be up to you, but the choices you make with that potential are what matters.
