It put the characters from the OT in the center of the story, and made them 100% irrelevant. Then it took everything they became and grew into over the three movies and put it all back to square one. Han went back to where he was when we met him, Leia went back to the beginning of her journey, and Luke went back to being a recluse with no friends. The new trilogy literally wiped out all character progression from the OT.
It was like Mass Effect 2 all over again. Which is one of my most hated games of all time.
