Densha Otoko is a heart warming, uplifting film. Its a wonderful underdog love story with great story telling. It incorporates a dynamic ensemble cast enabling it to strike resonance with almost any audience. As is to be expected with any foreign film, there will be increased appreciation if you understand the culture from which it comes, but even without an understanding of modern Japanese culture, or more specifically, Tokyo life-style, it is still a touching tale with very entertaining conventions.Being foreign, it can't be given a rating such as G, PG, PG-13, etc., but I would easily rate it as a PG movie. It is good, wholesome, and provides endearing redeeming qualities for every character. Based on an autobiographical novel, it lends itself to the believability that you seldom find in the romantic comedy genre. Naturally, some departures have been made from the original story for the sake of fluidity, but many of the storytelling mechanisms used in the movie are directly derived from the book, making it poetically interesting as well.I'm not one to give story details in reviews, but if you are concerned with the attractiveness of the story, note that the success of the original book spawned an anime series, a television series and this movie, all of which sustained impressive popularity in Japan.Summation: You can't go wrong with this pick.
