I don't want Sith to even be a part of the new trilogy even though I know they will. If you look just at the original 3 movies without any outside influence, Darth wasn't a title, it was just the name he chose for himself. The only reason he even had a lightsaber was because he used to be a Jedi, and he made it red because he was evil. The only reason the Sith are even a thing is because other Star Wars media, specifically the prequels, couldn't make people interested in anything new, so they had a bunch of guys called Darth with red lightsabers because Lucas didn't understand what made the original movies good. That's why I'm barely excited for the new movies because I feel like the additions to the mythology by the prequels has tainted all other Star Wars media.
