I haven't seen much of Korean movies but this one really made me sit on the edge. Rather than calling this the best 'zombie apocalypse' movie, I would call it the best movie illustrating the relationship between 'a father and his daughter'. I couldn't control my tears when Soo-An cries for her daddy to not leave when he gets infected. I would give it a zillion stars if I could. Recommended to everyone who loves a good suspenseful thrilling movie.
