First class all the way.

Rating: 9/10 (18 September 2016)

Train To Busan can be summed up in four words: zombies on a train. But what director Sang-ho Yeon does with this simple premise is extremely impressive, giving the somewhat tired zombie genre another jolt of life.
Using his confined location—a packed intercity train—to maximum effect, Yeon expertly ramps up the tension, the living gradually whittled down to a handful of passengers fighting for survival against the slavering undead (a bit like taking the last train home from Waterloo on a Saturday night).
There are some great ideas present that really add to the excitement, such as the zombies getting confused whenever the train enters a tunnel and swarming in numbers to break through barriers (with special effects easily on a par with those in World War Z). Surprisingly, the gore quotient is very low, but with such a rollicking pace, the lack of blood really isn't an issue.
Perhaps a touch too long at almost two hours to be perfect, Train to Busan is nevertheless one of the better zombie films to come out in recent years. Highly recommended. 8.5/10, rounded up to 9 for IMDb.
