“I’m sorry, it’s not good news … the chemotherapy has failed. We’re very good at end-of-life care.” These are the words heard by Ryan and Amy Green, parents of 5-year-old Joel who is dying of a brain tumour. Ryan is a video game designer, and he is dealing with his grief by making a game about the experience: That Dragon, Cancer. Self-doubt and the misunderstanding and criticism of others are just some of the hurdles he faces, as he and his family strive to understand and continue living under the watch of the dragon. This heart-rending journey, seen through the articulate and gently introspective eyes of a father, provides an unforgettable portrait of love and humanity; bring tissues.
