Some of the accents were a little off-putting, and the over-the-top violence really was not needed, but I really thought this was a fantastic film. I love Naomi Watts – why isn’t she in more films? Responding to thewilyfinipino below, the background for this film is the London that those of us who live here experience. The non-English pharmacy scene, the high-rise estates, the lack of actual Brits!
