Sorry, I'm not buying that baumer. No one has an objective opinion on what's good and bad - it doesn't matter how much of a minority you're in, everyone's opinion is as valid as one another's.
I don't have to "accept" that it's good, because I don't think it is.
If you look on RT (mainly from 3D rerelease), there are 21 critics who gave it a Rotten review. Are all those critics objectively wrong and must accept that it's a good film? 11 million audience members (31%) rated it as Rotten too, I guess their opinions are invalid too?
What about Avatar. It did amazingly in cinemas, highest grossing movie ever. Sold fantastically post-theatrical release, had 9 Oscar noms, is liked by people of all sorts (did great globally too), has a good IMDB score. Yet we all know Avatar has people who dislike it. Are they objectively wrong?
