The slight narrative, about human love being superior to a fallible machine run world without love, is able to deliver many moments that are tender and humorous, some flights-of-fancy that are beautifully photographed, and showoff throughout the filmmaker's great technical skills and inventive originality in storytelling. Chan-wook Park's style seems to lend itself well to violent action films, so it is nice to see him try something a little more tender and accomplish at it. That's not to say there isn't any action or violence but it is done with the right tone, context and with lots of humour. I absolutely loved it from start to finish, it's original, colourful and completely nuts (well, it does take place in a mental institution). I loved the ending too. You'd be 'nuts' to miss it! Just look at the pretty colours.
