I mean you can say everyone has their own opinion and they're all right from their perspective but this statement in itself is pointless. It's more meaningful to discuss why the majority opinion is better or why the minority opinion is better.
The thing about snobbery is that you referred to it as "art." Whenever I hear this I think "snob"
Okay.
For the record, I use the word art in the broadest and most inclusive possible sense. I would use "art" to describe literally any creative work, including television commercials and crayon artwork from three year-olds.
As for the majority opinion? Yeah, I mean, I get it. I don't think it proves anything, but that's less "screw public opinion" and more "I don't think there's any kind of objectively true judgement about art, whether we're talking about the opinions of so-called 'experts' or the general public."
(It may be worth noting that this entire discussion is within the context of me defending a movie that was mostly critically panned upon initial release...)
