One of the hardest things for a film to do, or a book (or any art, really), is to portray a truly good character who is also believable and human. It is a lot easier to portray truly wicked, depraved characters who are believable (i.e. The Joker, or anyone in The Departed). It is totally refreshing, then, to see a film like Happy-Go-Lucky, which is basically a study of one person’s commitment to living a happy, upbeat, glass-half-full life in contemporary London.
