While there are certainly well-made classic movies I find unappealing...The Graduate...I don't believe I've ever attempted to scold anyone else for enjoying them. I've certainly never advocated a movie be banned or censored. The idea of criminalizing a piece of art or entertainment, if only in peoples' minds, is one I find totally repellent.
Saturday Night Fever is not a polite movie. Or a feel-good buffet of sunny escapism. It's a frequently gritty slice-of-life character drama, stocked with complicated characters, illustrating some hard, uncomfortable truths.
