Train to Busan was one of the BEST movies I have ever watched. Different language or otherwise. However, this is not Train to Busan. Yes, it is set in the same universe, however if you expect it to be anything like the first movie—you’ll be mistaken. It’s action-packed, tear-jerking, and everything you’d expect to see from the original director of Train to Busan, but this movie focuses on POST-apocalyptic occurrences and doesn't center completely around zombies but more around people. A lot of reviews I’ve seen are from misguidance or expectations that won’t be filled. This isn’t a sequel. So enjoy it as it’s own movie! I personally found it very interesting and enjoyed the other all plot and the idea they were trying to portray by making zombies more of like a background accessory and less of the main story. It was interesting, give it a shot. :))
