It was also interesting to see the parent's point of view. In the film, we see a mom that is trying to both cope with her new son's reality while simultaneously mourning her daughter. When I transitioned, it was surprising to me that cis people in my life felt like they were both losing and gaining a person in their life. In my mind I would always be the same person. Still, the mother in 3 Generations is supportive, loving and it's realistic to show that she is able to be supporting and loving while still struggling with the idea of her child's transition.
3 Generation's Ray is one of the most realistic depictions of a transgender character I've yet seen in media. His strong desire to start HRT so that he can live as his true self is handled well and easily relatable for any transgender viewer. The depiction of his dysphoria is quite well done and I couldn't help but smile when (spoiler alert) he is finally able to start HRT and celebrates the important milestone with his family.
Unfortunately, the entire plot hinges on the idea that a kid in New York City is only able to get on hormones if both parents consent. This is an issue in 3 Generations because Ray's father is not in contact with him. In fact the father has moved on and is living in another town with a new family.
