This is an amazing Shin Chan film! This is by the same director as Adult Empire Strikes back, which is the most acclaimed Shin Chan film. This is literally the next film the director made right after that. This one is sadly very overlooked, probably because it is a Sengoku Japan period piece (Shin Chan gets sent back and time and is protected by a samurai). Very very interesting, funny, intense and dark film, has so much to say about how people of the Japan's modern era (of the time) can learn from the suffering and also the bravery of the Sengoku era. Actually beautifuland really dark and screwed up too... Great film!!
