wow, long post, glad I gave up on the argument between you two a lot of posts ago.
Anyway, I would just like to say that I don't think racism is the only theme of this movie. I think it is also saying about how isolated we have become, and how hard we find it to communicate with other people (despite the developments in communication technology!). People are much less community minded these days, and find it easier to distance themselves (and their actions) from other people, and not always think about the effect their behaviour has on people.
