In “Ginger Snaps,” lycanthropy works as the same metaphor for adolescence that telekinesis did in “Carrie” and “The Fury,” though the correlations are even more direct: hair growing in strange places, uncontrollable urges, the simultaneous desire to be accepted and to revel in being an outsider.
Brian De Palma's Carrie is another antecedent in the literal sense; thematically, though, Ginger Snaps is even closer to the body-horror cycle kicked off by (Canadian) filmmaker David Cronenberg in the late 1970s (especially his downright venereal Shivers and Rabid) and mainstreamed by Ridley Scott's Alien , itself fairly aghast at the particulars of reproductive processes.
Girls can be "sluts, virgins, teases and bitches," Ginger reasons, but no one will ever suspect that girls could do something like make a classmate mysteriously disappear (obviously, they haven't seen Carrie).
Working from a lively, unsparing script by Karen Walton, Canadian director John Fawcett touches on the same unsettling feelings evoked by Carrie, which was also fueled by the intense mortification that goes along with the first signs of womanhood.
John Fawcett’s Ginger Snaps devilishly reworks the menstrual horror film genre that seemingly began and ended with Brian De Palma’s Carrie.
No horror film since Carrie has made such use of the terrors of menstruation and puberty.
