As a person who practices poliamory, I think this is an excellent movie. It portraits most of the experiences that you might live on your polyamory journey. It's feel super realistic and positive. During the movie you will see their characters struggling with the same things that you might see in real life. But not only challenges, , positive and heartwarming scences will make you feel heard and understand by the author of this film.
A final and important thing is that this movie is a fantastic resource to explain polyamory to your monogamus friends and family. So if you have a family or friend that has stopped been monogamus, or If you are the one changing to a non monogamus relational option, get or rent It and invite everyone to watch It. It Will definitely help to understand the paradigm.
