The film proved to be a huge success at box office. So, it is be explained through a handful of different examples all mashed together. It is not lighthearted and I don’t recommend watching it if you are an easily depressed person or if you expect the same amount of action as in the recent Marvel movies. The movie is just one of the most controversial in Korea primarily on account of the explicit sex scenes. When an MCU movie makes my top five list, I normally walk from the theater free of question it has earned its spot. It’s a story people want to learn about.
