Great little film
Pretty impressive to see a smart film like this come out of the 1970s. I suppose you could call it feminist, but it's really a very human story about friendship and independence.
It's too rare for films to portray platonic relationships -- especially between women -- as realistic and complicated. There's a lot of nuance in the writing. I'm surprised this film isn't better known or embraced as an important work by a woman writer-director.
