I left out sexual orientation. Can’t forget that.
Maybe fewer women and nonwhites want to write reviews.
Time was women and homosexual men were the prominent film critics and buffs decades ago. It forever perverted and stunted the concept of what “classic” films were.
Later in the early 1960s other film societies (in Europe and revival screenings in America) started to explore horror films and defend that such genre pictures TOO could be classics (and Freaks went from being a banished MGM film sold to exploiter Dwain Esper in the 40s to a “Classic” that MGM claims to own again even though they sold it and dumped the negative in the ocean and screen it today with Esper’s additional exploitative opening reel).
