I wondered how can such a good movie with 7.3-8 rating could be missed and now I understood. The ratings are mostly by Koreans. It's such a stupid movie where a terminally ill mother can live for 15 years and a ghost can become as powerful as god by creating tornadoes to kill living ones. Such a silly concept where they have tried to force satire and seriousness together. And the trial what they say, are like watching cartoons. Gods who lick lollypops and gods who can't protect their own realms from ghouls. When the charge is that he wrote fake letters, guardian just says that he gave hope through fake letters and the gods feel so emotional, then grant him freedom. Also the hero thinks that he can reincarnate to take care of his mother in his previous life. So many stupidities.
