Technically we were talking about originality or lack there of in TFA.
Well definitely a step towards originality would be to make the Episode VII take place at least 100 years after the Battle of Endor. No Skywalkers, no Solos and preferably no Empire or remnants (though it makes sense in TFA since it’s only been 30 years). This way a completely new threat can be introduced and it would’t seem out of place. Also instead of a Dark Side Master at the helm we could make the supreme villain a government official that reigns over the Dark Side users and whatever you want to call the new army our heroes would face. Also it wouldn’t hurt to have different clans of Force Wielders with their own philosophies on how The Force should be used and on the galaxy could be ran.
Just a few ideas off the top of the dome.
