I was amazed by this movie, which achieves a level of naturalness and believability that are unusual in Hollywood. To admit that my heart sinks when Seth Rogen is in a movie is an understatement, but here he is used in the correct way - as the stoner friend who learns how to be a real friend. Although the subject matter is hard work and the film puts you through the ringer, it does this in an expert way. It takes you into the hopeless world of the hospital cancer wards, where doctors won't meet their patients eyes and can't explain their treatments properly, where therapists are out of their depth and patients die. But it does so with a comedic edge and with an intense respect for the truth of everyone's emotions.
Maybe it's a stretch for some to watch a film about cancer, where no-one's particularly good-looking or rich or powerful, but what does that say about what most audiences really fear? Two hundred years ago dying and death were part of life, but now they are hidden from view. A film like this reminds us of the simple fact that life ends, and most often, in modern life, it ends because of inoperable cancer. The subject needs to be explored, even laughed at, so that we can process it. This film achieves all this and more, with a touching, nuanced central performance from Joseph Gordon-Hewitt, and lovely work by Angelica Houston.
