A well-written and acted drama and medical crime based on the background story of a young boy experiencing the pain of an operation, due to the fact that the painkillers do not work. Crucial point of the movie is the fact that the general motive is clear, however it is not known who the killer is. Psycho games included, "Return" is a typical modern Korean crime movie involving emotion, unexpected twists in the storyline and a good acting of all involved personnel. Despite a few not explained background connections at the beginning of the movie is the picture in general a haunting piece of film work, especially due to the explicit showing of clinical operations and, for my part, the use of needles.
