This is one hell of a hilarious movie. As the other reviewer Shaz22 said, this movie teaches you an important lesson. However the way it's done is what distinguishes it. Being a fan of mystery, this movie sets up the story and its mysteries perfectly in such an entertaining and unpredictable way that makes it total fun watch that you don't feel the time. Some hints given you can catch on pretty early while others totally gets you off guard. The movie tells the story of a number of individuals that get involved with our hero, the king of apology, Ryoro Kurojima, in different timelines through different point of views which makes the whole movie into puzzle pieces that all goes into place by the end of it. Of course this movie wouldn't have been the same if it wasn't for it's cast. Abe Sadao sure was brilliantly casted but we also have the lovely Inoue Mao in a yet totally different character that we're used to, Takenouchi Yutaka, Takahashi Katsumi, Matsuyuki Yasuko, Okada Masaki as well as others and each one has his own distinct way of being hilarious. And when you thought it couldn't get any more hilarious, the ending is beats that expectation. It's funny that throughout the movie they give you the hint, you just never catch on until the director decides to let you catch on. I totally recomment that movie for anyone, but specially for those you appreciate Japanese comedy. As I mentioned earlier, for whats worth, I found the movie also had a nice message to transmit that isn't even done subtly but somehow doesn't feel preachy.
