Warning: You should not watch this movie if you ever plan on eating Ramen again without having being haunted by some catchy music.
I got so many Yakuza game vibes while watching this movie, that I think that it would not surprise anyone if it was just a submission for Kiryu. It had a good mix of trashy story and characters, some fighting with different objects and Yakuza rivalry. In addition, it had some catchy songs about Ramen. Overall it's really enjoyable, just don't expect to much quality. Oh, and don't expect any gore because there is none.
