"Evidence #1" is meaningless. You and I both know that box office numbers and audience reviews are not inclusive. Good movies can get low financial results and big $$$$$ does not make a good movie. People, like you, were also turned off by how bad TLJ is. People are putting their money where their mouth is, for once. It's a double-edged sword, as they're sacrificing a good experience to spite Lucasfilm.
"Critical reaction" from other movies is also meaningless. Surprise! The critics loved TLJ and TROS carps on it. Were you expecting the critics to positively review a movie devoid of PC that gives middle fingers to their favorite modern Star Wars film? Come on, man.
Your retort is devoid of actual evidence. The movie is generally 'good' with an audience score that most people would say, "fair". So, people who have actually seen the movie agree with its score, but someone who has not seen the movie cries "tampering" Do you see where the logic takes place?
