Tensed, brutal/gory n very engaging. This is how zombie genre shud be.

Rating: 10/10 (17 September 2018)

I am writing this review again.
I don't know how n y my earlier review of this film got deleted. I am a big fan of Korean thrillers n a bit bias but this film doesn't deserve anything below 9 from horror n thriller fans.
I find movies set in a running train intriguing.
The aerial scenes were very well shot. The cinematography is spectacular n the editing crispy.
The film is loaded with tension n mayhem throughout.
The best character is the husband of the pregnant woman. One helluva selfless fella.
Horror, especially zombie fans will not b disappointed.
