That is a pretty good imagination that you have there, tell me exactly how loud they would howl if Disney made a good follow on movie to the original series?
I think it is pretty easy for the haters to just lump everything together under a label like EU and then bash it, as if everything in the EU was somekind of literary masterpiece, and then make some far fetched claim that people hate x becuase they changed it. Of course people are going to look at everything else that is around and compare it.
Never claimed the EU was great. I did say. They could have learnt from it and cherry picked the good parts.
EU had plenty of interesting female force users for example. Rey is kinda boring because of her lack of character development/struggle. Her and Kylo have basically made 0 progression as characters since the start of TFA. There's no emotion there because the new character s barely know each other and Rey didn't have Beru and Lars to get mowed down.
The pacing is also off along with big plot holes. Finn for example can't pilot in TFA that's what Poe is for no problem in TLJ though despite it being hours or days after TFA. There's a 3 year gap between ESB and ANH and even if it's not clear in the movies how much time had passed you know some time had passed as the rebels have had time to build a new base.
It's just nonsensical stuff like this that TLJ screwed up with along with fairly minimal character development
