Stuart: A Life Backwards
Although the story is not a happy one, homelessness rarely is, it has a delightful charm about it, and is full of humour. I like this unlikely match between violent alcoholic and writer, and the very idea that these two people had a friendship; both from wildly different backgrounds and futures, but ultimately able to appreciate and love each other as they shared the present. You can't help but love them yourself.
I spent many a time with the alcoholic homeless people of Cambridge, and to revisit that scene, albeit by television, I found rather moving.
