Professional wrestling is a unique entity. What is good and what is bad is generally not decided by the people performing it but by the fans who watch it.
Lou Theisz, Ric Flair, Hulk Hogan, Steve Austin, John Cena, Daniel Bryan, in the US, they changed wrestling forever in their own eras. Not because they were better than everyone else, but because they caught on with the fans. So other wrestlers began to imitate them to keep up. Lucha culture has their Era changers. Japan has theirs. Europe has theirs.
With most sports, or with most tv shows/movies, you get what you get. And you either like it or you hate it. It won't change anything. But in wrestling, what you support and what you reject changes what happens next. Maybe that's one of the things that makes it great.
