Well, yes

David Thomson, reviewing Tom Kalin's tentative film career and his pretty good (and, until Savage Grace, only) film Swoon:

It was hard to see Swoon without detecting a gay film, but that mood was no more pressing or less complicated than the fact that Goodfellas was a claim made for heterosexuality in an essentially gay world. In other words, no film is simply about sex, even if nearly every film is also always about sex.
