It is a delightful movie about their friendship and how they support one another. The creative tension comes from a romantic attraction which never becomes consummated because they both love another.
This is a low budget movie which has been nominated for several awards. It is a fiction film that works so well some viewers have mistaken it for a documentary. It raises the perennial question raised in the movie When Harry Met Sally, can a man and woman just be friends?
I recommend this film.
