This movie is a gentle and deep melodrama using the July 2005 terrorist acts as a jumping off point for telling about clashing cultures united in grief. The story is certainly a hard look at racial biases and is strongly backed by Blethyn's character, whose repressed hysteria clashes with Kouyaté's attitude (more similar to a calm resignation). The director has also depicted a very serious and fascinating study on how Londoners were unprepared to react to such an emergency. Overall this is a poignant and insight-filled take on prejudice in post-11/7 London, well acted and directed. There have been other "Londoner" films about the same subject (or about terrorism in the UK) but this is the best by far in my opinion.
