I don't know where to begin. This film is an absolute masterpiece. From the director to the actors, each part of every scene was incredible. At first, I was a little hesitant to watch this. Boy, am I glad I did!

I thought it was going to be your typical horror movie- zombie outbreak, zombies kill everyone, hero saves the day and all is well. This was so much more than that. I grew attached to each character in this film. I felt their pain, their anger and their sadness. It was a heartbreaking scene for me when Jin Hee got bitten. I could feel the devastation of Yeong Guk, and as cruel as this sounds, I'm sort of glad they went out together- it's how their story ended. They never officially told each other about their feelings, so having them die together showed their love.
Also, when Sang Hwa and Seo Woo I felt the pain Sung Kyung and Soo An. Even I started sobbing when Seo Woo 'jumped' of the train. In the end, his daughter realised that her father loved her and got to say one final goodbye.

Every moment had me hanging in the edge of my seat, and although I already know what happens, I will definitely watch this again. I have no doubt that I will be just as nervous of heartbroken when re-watching it for the fifth time!
