If 4 came out today, like assuming they made 1,2,3 and then 4 came out, it would be panned just like the rest. This is more an effect of the internet than anything else. It is a human hate machine. Social media is the nuclear bomb of bullying and hatred, nobody is immune. Least of anyone who actually creates anything.
I am disappointed that 8 wasn’t really great but that is only because I thought 7 was outstanding and it damaged the story 7 started to tell irreparably. I enjoyed 9 but I see where it was really crippled by having to not only correct misdeeds in 8 but also make up for the derailment of the story. Spoilers coming.
We all have to admit that is a failure of the story that suddenly after two thirds of the trilogy is complete, they have to introduce the main villain in the crawl as something as ham handed as “sudden voice from the sky.” Adding to it that said main villain was killed 30 years ago in the movie release timeline and you see the crazy gyrations 8’s terrible mangling of the plot caused. It also calls into question the entire first trilogy because Vader’s sacrifice was invalidated by the fact that the emperor was apparently not killed at the end of 6.
so I get the disappointment, but the hate and rage I have seen on the “superfan” channels is fueled by something else I think.
