This movie reviewer hates the movie because it doesn't say the latest things about homosexuality. But the author badly contradicts himself in adjacent paragraphs:
" It offers the standard 1950s melodramatic theory of Alexander's sexual orientation: the scheming, sexualized, domineering mother, and the distant, uncaring father. So much for today's theories of genetic predetermination. ... His bisexuality, after all, is fairly commonplace in the world of this movie,..."
See, the movie is not hip to the "truth" about homos because it doesn't assert that homosexuality is genetically determined. Of course, he says there were a LOT of gays back then. Why? A bad accident at the HellenChem (tm) chemical refinery plant? Or had natural selection simply not had as much time to weed out the homosexual population?
Good catch.
