Halloween is the perfect time to brush up on the rich history of queer horror cinema. The genre might feel more standardised in the age of Fear Street, but it was rather more subversive around the time of Ginger Snaps, John Fawcett’s sly, perverse feminist werewolf movie. In it, a teenage girl’s lycanthrope transformation deepens and darkens her already intense relationship with her sister. It’s luridly frightening and grimly funny, weaving alternative identities and longings through the relationship at its centre.
