I watched the drama a couple of months ago and I thought it was lacking an explanation or something in the end that I thought hopefully would be resolved in this movie. However, I just spent two hours of my life watching the exact same thing with a slightly different ending, which is why I decided to rate the film this low. I was not a fan of the original story even though I was digging that plot but either it was badly executed or I'm not used yet to Japanese storytelling. I really liked the main actress though so I'll make sure to check out more of her works. Also, if someone is reading this and trying to decide whether to watch the movie or the drama I'd go for the drama. It has more of an open ending in comparison but it was overall more enjoyable.
