Asian girl with bad haircut I think is the main thrust of their argument.
They wanted Luke Skywalker to be not sad and just be a badass and not die and also they don't like women being heroes or appearing while not white and also they wanted Rey to be related to Luke Skywalker because reasons
Many people imagined a different outcome for their hero after 30 years I guess, but no single work will ever be able to live up to the old extended canon and the mountains of fan fiction in people's heads.
This is unfair. I didn't like the movie and I thought it was a fucking mess -- It was so bad it made me stop caring about SW after being a life long fan -- And it has nothing to do with asians or women or haircuts or Luke not being badass enough. The problems were literally everything else but those things. The movie is a *fucking* mess where much of what happens and much of what people do makes no logical sense. Shockingly they had no plan at the outset and let directors make each episode up as they went along and it shoowwwsss. It's hard to take it seriously when there's no one overseeing the overall storyline who is taking it seriously.
You're free to disagree and like the movie, but it's so frustrating being painted as a manbaby outraged about SJWs just because I didn't.
