I have no idea really... But if I asked them they would either dodge the question, or go off on a long explanation that leaves me feeling like I did something wrong by asking and still not understanding why I can't watch it...
Why? I see it as being really good and actually complements Christianity really good. Jedi values and themselves represent perfect Christian. Selfless caring for others and when need to fight they are still good unlike most crusaders. They even have similar rules of not marrying and having children like catholic priests monks etc have.
