Er, yeah, so here's a bit more from this book I've been reading. It is a critical look at Bride of Frankenstein (1935).
The author claims that homosexuality is an important theme in the movie.
Er, yeah, 'cos no two things go together like the story of Frankenstein and homosexuality. The author points to the fact that a fair amount of the film's cast were gay (so?), and even goes so far as to say that the only meaningful relationship in the movie is between two males (Frankenstein's monster and a blind man who befriends him). This is stretching it a bit. No, it's stretching it a lot. The relationship between Frankenstein's monster and the hermit is platonic, and therefore nothing to do with homosexuality or gay sexual relationships.
And then there's this doozy, quote : [Dr] Pretorius tells Henry [Frankenstein] with an arched eyebrow that 'I grow my creatures ... as nature does, from seed', possibly a reference to masturbation ... - er no, just no.
Y'know, there's interesting movie analysis, and there's talking bollocks. We must not let ourselves stray into the latter when we're engaging in the former.
To be fair to the author, he does resist the temptation to scrabble around for metaphor during his analysis of The Texas Chainsaw Massacre (1974), which is spot on incidentally. TCM is just a pure horror film, plain and simple, designed to scare the bejesus out of 70s cinema-goers.
