Synopsis: While a zombie-virus breaks out in South Korea, a couple of passengers struggle to survive on the train from Seoul to Busan. – (Source)

The Good:
The characters really stand out in this movie from Seok-woo who starts oout as a detached and self-absorbed father to the cute as a button Su-an but who eventually becomes a selfless hero to married couple SUng-Gyeong (who is extremely pregnant) and Sang-Wa (a good-natured hulk of a man) to the all around awful businessman Yong-Suk, who is one of my favorite types of character in a survival horror movie. He is the Burke character from ALIENS, a totally selfish asshat who endangers everyone to save himself.
The movie also maintains a consistently high level of tension for long stretches at a time which is quite a feat. That ramped up tensions makes sitting through TRAIN TO BUSAN like being on a rollercoaster emotionally as you are so caught up in just who will live or die and how any of the folks trying to survive are ever going to escape the zombie hordes.
I also loved the initial zombie transformation sequences. The way the infected person’s body convulsed and contorted was horrific.

The Bad:
There are a few sections of the film where things slow down to a crawl and it feels really unnecessary. As a viewer all you want is for zombies to start chasing people again.

The Ugly:
That ending was some seriously treacly bullcrap. A movie this unrelentingly tense needed a much better ending than the one we got.

Final Verdict: A high adrenaline thrill ride that comes off like an amalgamation of SNAKES ON A PLANE and WORLD WAR Z yet TRAIN TO BUSAN is an infinitely better movie than both of those films I mentioned. Despite a week ending, this is a truly worthy addition to the annals of great zombie horror films.

Grade: B+
