When Ginger starts growing fangs and claws, how come nobody notices? Not her teachers, not her classmates, not even her parents.
And, more disturbingly, why do the early stages of fangdom make her look so hot?
I don’t get the reference, and it sounds like I’d like to. Does her school notice when she finally snaps?
In the film, it’s established very early on that sister Brigitte and Ginger are very deeply odd.
I don’t think Ginger’s that odd, until she becomes a werewolf.
The secret to great ginger snaps is to triple the amount of spices and add vanilla.
Did she go all psycho on Mary Ann? “Gilligan always liked you best. Bitch!”
This is a great film, and would probably be the second best werewolf film ever (after American Werewolf in London) were it not handicapped by a poverty row budget. The early signs of Ginger’s transformation were merely slightly extended teeth, a couple of blond streaks in her hair, and a major level up in hotness. Easy to overlook. 
The fully transformed werewolf, on the other hand, was not a triumph of makeup or costuming. Curiously, in the two subsequent films, the quality of the effects was reversed: the early transformation looked dreadful, but the wolves were excellent.
In the third movie, there is a scene with a hooded and caped Ginger standing between two rows of wolves, brushing her hands lightly across their backs as they stalk past her. A most striking image from an admittedly lower-quality, but very atmospheric film.
Good to know it’s not just me that thinks that.
We all understand that the werewolf thing is just a metaphor for a young woman’s experience in puberty/sexual awaking, yes?
If so, there is the answer to all the OP’s questions.
Well of course. There’s a reason for all that naked werewolf humping in the various Howling films.
It doesn’t hurt that Ginger is the lovely Katharine Isabelle, now recently come to my attention as Margot Verger in NBC’s HANNIBAL.
