I really don't know by what basis the previous two reviewers were judging this excellent documentary, but I found it it excellent and educational. It covers a sensitive issue from every angle, including previously held beliefs that have now been discredited and talking to tragic victims of previously enforced "expert" opinions. The information presented is well-balanced and does not advocate any particular side whatsoever leaving the viewer to make up their own mind based on the facts presented. Viewpoints are taken from parents of children with gender dysphoria, children with the condition as well as adults and teenagers with the condition. I recommend watching it whether you know nothing, a little or a lot on this subject. Bear in mind also that this was commissioned for The National Geographic, which has a track-record of the highest quality educational content, add that to a multi EMMY award-winning journalist, Katie Couric, that has worked at all three major U.S. networks, you can decide for yourself.
