On first seeing the sheet covering I was a bit taken aback as I thought it was a bit cheesy. However, as the story progresses, it becomes clear that the sheet is a clever mechanism to portray his ghostly presence in spirit form instead of just seeing him in a translucent state. The story is touching and quite sad and its use of time shifting brings an interesting concept. Unlike many other movies, this one has stuck in my memory due to its unusual nature and technique.
