From my personal perspective, I found the film gave an alternative story about the parents' choice. Alternatives can always give hope that we are not bound to follow mainstream practices, which in the film, as in most countries, is about having cosmetic surgery to "correct the aberrations", to force one or the other sex upon a child. Not only did I find Alex's story poignant, but her parents' story was powerfully portrayed.
However where I find the title of the film misleading, is that all of the XXY boys and men I know do not have ambiguous genitals. They have male genitals and are recognized as boys at birth. My son has XXY syndrome and finds it distressing to be asked if he is a hermaphrodite. So while the film portrays the difficulty of having a child with an INTERSEX condition, and the difficulty of finding your sexual identity as a person with an INTERSEX condition, I think that the title does not help those who have XXY to confront other people's curiosity and lack of consideration for those who are different.
The film should be entitled differently.
