This film is as visually rich as they come. If you love films for the images then I wouldn't hesitate to see this film (along with its superior sister- 'Chungking Express'). The camerawork by Chris Doyle is really something else, and that is where my main appreciation for this film lies.
Others will argue that it is also a touching account of inner city loneliness, and it is to an extent- but in the end the narrative content doesn't do enough to carry the weight of the film. The film starts promisingly but even fans of the film will probably concede that after the initial introduction to the films themes and style, it fails to take this anywhere spectacular. Instead, the viewer has to settle for the images, which in a film of this beauty isn't that hard to do.
To sum up: Pretty, but Pretty empty. (Of the other two Wong Kar-Wai films I have seen- Chungking Express is more highly recommended- but 'Happy Together' even more so. 'Happy Together' is not quite as flashy but in my opinion- just as beautiful but a fuller, more profound foray into Wong's predominately visual cinema.)
