First and foremost: Don't confuse a review of this film with a review of the practices involved. (I've seen at least one negative review of this film that was clearly by someone who had not seen the film, but wished only to voice an opinion about the general subject matter).
See this film. Pro-choice, pro-life, undecided? Doesn't matter. See this film. It will only help you to better the subject.
This film is the best documentary I've seen. I don't mean just because the content is amazing, of course, but the quality of the portrayal is also almost shockingly good. A number of the filming techniques did an *extremely* effective job of letting us see insides the minds and hearts of both doctors *and* patients.
In a topic as emotionally charged as what this film covers, it's easy to get caught up in the subject as "abstract." This film helps us to see the real impact and effects these people - and practices - have. It's not always pretty, and it can be very difficult to watch, but I feel significantly more connected to the whole subject now.
Yes, the film leans in some ways toward "pro-choice," but it in fact makes some very clear points about just how difficult that choice is. I won't spoil it, but the most intense moment of the film for me happened right there. And the film doesn't vilify the pro-life people - they're ever-present, as in real life, but they are portrayed honestly as well. It's clear they are as passionate as the doctors.
This is just, overall, a very brutally honest film.
I had the good fortune to see this in a small theater, and one of the directors did a video-chat with the theater as a Q & A. That was a nice touch, but my 10/10 review was cinched the moment the film ended.
