I loved this movie. The characters are all credibily played by the cast and each has a depth of emotion not usually portrayed so well. The style is retro '70s and the film and characters ooze style throughout, particularly in dressing for the occassion or task. Technically the film is excellent, with great lighting, image quality and camera work.
The sountrack has some great songs that are very appropriately chosen for the mood and emotions of a scene, particularly the beautiful matching of the Bee Gees hit 'How Can You Mend A Broken Heart' used in a multi main character scene when everything begins to fall apart.
If you are under 25 or your bag is gratuous violence and fast action, this movie is probably not for you, but if you like character relationships and deep intrigue at a pace you can follow, you are likely to really enjoy it.
