I like these kind of dramas/movies and though I haven't watched any of its anime version or read its manga and I think it's a good thing cause I was able to enjoy the movie. I love the characters and how it was portrayed by the actors. I find the storyline unique and that kept me watching this movie till the end. The music was cool enough for me. I plan on watching the anime but I'm glad I watched the movie first before my impression will be spoilt if I did the other way. I will surely watch this again. It's one of the classic Japanese movies worth re-watching because of it's unique plot and especially if you are a fan of it. I recommend it especially if you want to watch something with your friends. This is certainly worth a try and one of the best Japanese movies.
