Train to Busan is one of the greatest zombie movies imo
I recently watched TOB again after first seeing it in theaters, and I got to say, it still holds up. This movie, unlike some films, actually made the audience sympathize with the characters, even the main protagonist Seok-woo, even if he was kind of a douche at times. The movie also did a great job at literally telling its audience "South Korea is F'd"
Me personally, I liked the film because these characters had extremely limited resources. They didn't have guns, they didn't have any knives or axes. All they had were blunt weapons. Baseball bats, riot gear, etc. So they couldn't just kill the zombies, they had to just knock them out and pray they wouldn't rise again. I think that was one of the fear factors for me. Also, these zombies were FAST!, and that's something you do not want to brush aside if an actual zombie apocalypse happens.
I'm not a person who cries during a movie, but holy crap I was ingesting snot and wetting my shirt when Seok-woo committed suicide. His daughter's screams, and the fact that the pregnant lady was holding her back to prevent her from going to her dad destroyed me so much. And by the end I couldn't even think "Yay they made it!". The final two survivors went through so much, I cant comprehend how f'd up both of them are.
Overall an awesome movie worth watching. The second film was great also but the first one is truly one of the greatest zombies movies imo.
