There was no clear arc to the three stories..Abrams said it himself they had not made a clear defined story. With all his faults Lucas knew where the prequels were going from the beginning..These new trilogies had plots not developed, nor answered..and the first one was just a rehash of A New Hope..I once went through and picked out the similarities..it was ridiculous..
What truly is unforgivable is that they basically made what Luke, Han, and Leia, had accomplished redundant..nothing had changed..There was still the Empire, just under a different name The New Order, and still the Rebels, ie the Resistance..
Just on a note Luke, he was supposed to be one of the most powerful Jedi ever..yet we get this paranoid, skeptical, weak shadow.. we should have got the warrior we’d all been waiting for.. just woeful..
