I highly recommend watching this movie if you've seen the first. If not, then watch it...or else. First off, let me say that a few of the main characters have been replaced, which is sad, but at the same time kind of refreshing? Okay, so not so much for me. I liked the old cast and that may be the only reason I've rated this a two and a half stars. Anyways, if they don't make a third one, I might as well have never watched this... Some big fans of Nana have said that the movies were not so great. They are slow, but having watched them, I feel like reading the manga and watching the anime. The following synopsis is taken from
MySoju.com, where you can find the links to watch the film with subtitles.
Description: Taking place shortly after the end of the first film, Nana 2 focuses more on Komatsu Nana (Hachi/Hachiko)and her love life. Romance develops between Hachi and TRAPNEST's bassist Takumi as well as with the Black Stones' guitarist Nobu. Meanwhile, Nana works hard for her band while trying to find happiness. Both girls struggle through life, and try to keep their friendship from falling apart. More information on the story at Nana.
