I dare say anyone who has reached middle age has several friends or acquaintances who have suffered and died from long term diseases, and I'm sure that no two peoples attitude to dying would be the same either. There lies the problem with this movie. I can't say I recognise any friends in the characters portrayed, but I'm sure others do. Complaining about a movie for not being real simply because it's not your reality doesn't make the writer or director wrong. The one similarity between all humans is our difference.
