I originally saw this movie on VHS (with subtitles, which I loaned to a friend and never got it back). So when it came out on DVD I placed a special order for it and cost me $100 and was really worth it and worth the wait. The only draw back is that the Japanese DVD release does not include any subtitles at all and I am trying to have subtitles added to this film.
A friend of mind showed it to me and I was totally blown away. If you love time travel movies, this film has a different concept or approach on it, no time machines involved. Though there might be parts of the movie which is a little bit disturbing or can be offensive to some but the way it was made was in good taste.
