This movie was very similar to Train to Busan but unlike Train to Busan which was superior to this movie, this movie had one big plot device in the little girl. I mean, the entire plot revolves around the little girl ie. when she gets lost, having to save her, etc and at one point, it starts getting redundant. There's also a K-drama-like romance between the main leads which annoys you as a viewer coz here's a guy who does so much for the female lead but she shows no appreciation or gratitude throughout the entirety of the movie. The female lead was literally a cold bitch to the main lead who was saving her ass and her daughter's time after time and it made me wish her death in the movie due to how utterly annoyed I was at her personality. She was so selfish to the point that she basically put the life of the kid who survives the infection and has anti-bodies to cure the disease all to save her daughter. Not to mention how she literally tells this kid to stay alive as he's about to die after being stabbed just so that she can use his anti-bodies. When the female lead got shot in the end during the climax of the movie, I was happy but then I realized that she was shot in the shoulder and its only a flesh wound and not fatal. Which reminds me of how predictable the movie is during the end. Its not gonna make you cry or anything unlike Train to Busan did. What I love about Train to Busan is that it explores the struggle of a father and daughter through a zombie apocalypse on that train and it doesn't use the daughter as a constant plot device like this movie does to the point that it becomes annoying. If your're having second thoughts about watching this, watch Train to Busan instead of this K-dramaish movie about a flu infestation and a very annoying female lead.
