In fairness to KK, she tried her best to push TFA to 2016, adding a year which would have allowed for a more thought out trilogy.
Disney was eager to make back their 4 billion dollar investment so they demanded a late 2015 release.
Ultimately it was Disney’s greed that was the downfall of this trilogy.
Disney played a part yes. But KK is the one that allowed all directors to do their own thing. KK is the one that DID NOT WANT LUKE IN EPISODE 7 because he would take away the attention from the new characters. Even with Disneys demands what happened is still on KK. No schedule demands are responsible for Crazy KKs terrible creative decisions only Crazy KK is responsible
