Describe a movie you enjoy watching

Honestly, the first reason that attracted me to this movie was the main cast. I am a big fan of Gong Yoo. I still remember how excited I was when I knew Gong Yoo would play Seok - Woo in the movie. But after watching the movie, I realized it was a great movie. Not only because of the excellent performance of the cast, realistic effects, but also thanks to the film's profound content. The context of the film is when Korea broke out with a strange virus that turns people into zombies. These zombies attack people aggressively and become diseases. One of them got on the train from Seoul to Busan, then the death game began with fast, dramatic, scary hunts with the rescue of the main character with many surprise factors. However, the most excellent thing about the film lies in the aspect of exploiting human psychology. The train itself is a miniature model of society from rich to poor, from good to evil. Only in times of danger can the true nature of each person be revealed.
