Incoherent, a waste of characters and maybe even insulting !

Rating: 2/10 (23 December 2017)

First thing. No, I'm not a bot. I've watched the movie in the theatre, thought about watching it a second time, but I really did not like many things in this movie. So instead of giving Disney more of my money, I've came here to express my point of view.
The director ignored many aspects and plots from previous movies and novels of the franchise. Even from The Force Awakens.
I felt that many characters were thrown there just to be a mean to an end, even the big ones. Which I think it's not a big problem if you are making a movie in a new universe, or trying to push a new franchise/saga. But it can be a big problem on a well stabilished universe like this.
A lot of things that could have been or needed to be explained, are just ignored or like Rian Johnson himself later said "aren't important to the history", or "weren't important in the 70s movie".
They had an oportunity to make an amazing trilogy, where the old character passes the torch to the new hero and teaches her about the things that he did right and wrong, so she can become even stronger than him. And they could have done it in a way that feels respectful, nostalgic, coherent with the character and at the same time showing that he is not a perfect being.
But they didn't. And in my point of view, there are things in this movie that some Star Wars fans may find wrong, incoherent and in some cases even downright insulting.
Where are the true critics ? The ones that aren't afraid to tell that this is a horrible Star Wars movie and even harmful to the franchise.
