I agree, we should ignore the gender politics of this movie and it's detractors and that whole argument entirely. That has nothing to do with whether the movie is any good.
> But "a great action flick to go see if you are bored on a Saturday night" is what a Star Wars film is supposed to be.
Yes, but it's also supposed to be a continuing story. It's a serialized, epic, swashbuckling space opera. While TLJ is still a space opera, it doesn't follow the same tone and the story doesn't follow the same beats.
It's fine if you want to tell a story like TLJ about disillusionment and being disappointed with your heroes and discovering that the real world isn't about one ship destroying the Death Star. But taking that story and putting it in the Star Wars universe as a main entry in the series doesn't work. That's not what people want to see in a Star Wars movie. People go to a Star Wars movie to see the hero destroy the Death Star! You can't take any story with any characters and any plot elements and place it in the Star War Universe and magically have a Star Wars movie. It's the same reason you can't just have a movie with a Deloran and time travel and make a Back to the Future movie. It's the same reason the Ghostbusters remake was bad. It's the same reason the Mad Max remake was good. It's the same reason Infinity War was good. It's the same reason Batman v Superman was bad. You have to have some respect for the tone, themes, and plots of what came before. TLJ disrespects it's audience's desires by disrespecting the draw of the source material.
