Well, the fans pissed by Last jedi are not butthurted, because there were unexpected changes. They are pissed because, the plot o the movie is **** and the everything happening on screen does nto make sense:
1) Rey as a character is a wonder kid. She defeats Kylo, she defeats Pretorian guard, she even beats Luke! With zero training. She can use the force and do everything right without any effort. When there is no risk and no cost in doing it, it is boring.
2) The whole plot with chasing rebel fleet is bullshit. They could jump out of hyperspace from another side, so they could screw the fleet between two destroyers. Or they could deploy TIE squadron to shoot them down.
3) First Order is weak. They are just a bunch of idiots unable to use the power properly. Where are unbeatable characters like Vader, Thrawn, Tarkin etc.
4) Snoke / Kylo story is too weak. The whole killing point is too vague and too fragile to be successful, or Snoke is far weaker than Emperor and vader was.
5) If Poe was told about the escape plan (why he was not, I do not understand), than he would not plan to send finn and rose to that casino planet and that would not result than into pointless killing of escape pods.
6) Battle on Crait is again military ****. Why the **** those AT-MT gorillas did not shoot down Finns speeder? How Rose managed to get back in time to save Finn, why she was trying to save him in the first place when this would kill even more people and finally, why the were not shoot donw by troops/tanks when they crashed down?
7) What is the opening point for eiposode IX? The movie felt like final episode, not the middle one, there is no open plot.
And finally, the issue I personally have with the movie:
The disgrace they made to Luke Skywalker and mainly to Mark Hamill himslef.Everyone knows, that Carrie was using drugs and being little bit crazy and that Harrison did not like star wars fans at all. But Mark Hamill was always the one visiting cons, speaking to fans, loving the universe they created 40 years ago. Then he was lured into this bullshit movie, he naturally could not say no to playing in it (because whole world would hate him) and then he was forced to play his life-defining character in a way, which he was not comfortable with, he did not like and he did not approve and understand. And he even did not receive any dignity in death on screen. He jsut passed away like some tired old hermit. That was ******* worst thing I ever seen on screen, noone deserves this. He warned us several times, that this movie is **** even he does not like, we should listen and never watch.
