I just watched "Red Without Blue" about the identical twins where one of them is trans and the other is gay, and about how their lives and relationships change over several years, it was pretty well done. The trans twin Claire says (paraphrasing) "I wasn't born a man or a woman, instead the process of changing was the path I was born into," which I could identify with really well and I thought was really well said.
I also watched "American Transgender" the National Geographic one that spotlights three different trans people, including Claire from Red Without Blue, and it was all right. One of them said, "I'm willing to be me regardless of the consequences" which I think sums it up for many of us.
Any other good trans documentaries anyone can recommend?
