I watched it on Channel 4 + 1. It was interesting and contained footage of children and teens in the US who identify as transgendered - in both directions - along with their parents, and doctors, but every time that the (female sounding and female named British) narrator called the child/teen by their birth pronoun instead of their chosen/identifying pronoun it really grated on me. Why even do that when everyone else (parents, siblings, teachers and the doctors) called them by their identifying pronoun? Was it just to piss them and the viewers (like me) off? Every time she did it I wanted to throw something at the TV or scream at her to just Get It Right! Yeah, I know - she did not write the script - but she did agree to speak it!
