I watched the movie, and I was extremely moved by it... I spent about half of the time crying. The only reason I watched the movie is a desire to know what trans-ignorant people are seeing: this was an educational film to most people. In that, I was very disappointed.
First off, the factual inaccuracies regarding surgery. My mom is already freaked out about this, and if she watches the movie, her panicky tendency will go into overdrive (not, as I've told her many times, that I'm even remotely interested in surgery... but she isn't the only mom in this position). The movie portrays the relatively safe operation that dozens of surgeons perform every day as extremely risky... whereas the actual complication was organ rejection, which is still pretty risky.
Second, there were way too many trans tropes. While some may be historically accurate, there isn't just a single story to tell, and I really dislike how Lili was portrayed: my principal complaint is that the movie repeats the "oh, you're transgender, so you must be gay now" trope. Also, Gerda is almost unwaveringly supportive of Lili... Lili is supportive of Gerda's career in the first part of the movie, and then focuses entirely on herself and stops reciprocating that support altogether: once she discovers that she's transgender, there's no depth left to her character.
