If you've ever lost someone to cancer, don't watch this movie as it does not properly capture the struggle or the ugly reality the way that Matthew Teague's essay did. If you relate to this movie at all, it's not for you. I had the honor and misfortune of living this film, in the role of Dane, when my mother was diagnosed with cervical cancer (around the same time that this movie takes place in fact) I paused my life to take care of her and it is an ugly experience.
The last half our of this film is incredible, it's exactly what I expected from it and exactly what I was hoping for, but the first hour and a half is the same feel-good drivel that supposedly inspired Mr. Teague to write his essay in the first place. His story however, was completely sanitized for the general public, if you have any connection with the story at all, skip this one, it'll just make you angry.
As a final note, if you haven't read the incredible essay that Mr. Teague published in Esquire magazine in (I believe) 2015 and intend to watch this film, watch the film first, and then read the essay. The essay is a most more honest retrospective of the struggle of a terminal diagnoses as well as the battle with cancer.
