A man who is at his middle ages, works for Italian mafia, has no family, his hobby is watching porno DVDs, and yoghurt lover got an unnatural super power by accident.
I'm glad that this hero was inspired by a Japanese animation but unfortunately I don't have any knowledge of that animation. If you like other hero's movies very much, you might be get less fun or disappointed.
I doubt that it'd fit for children even this's a hero movie.
