The movie was actually just a bit better than average. It was a good watch, suspenseful at times but most of the time it was just okay. I feel like they could have done a lot better. The plot is a bit cliché and it was just a typical zombie movie. There are scenes where you would really question the actions of both the zombies and the lead characters. There are a lot of plot holes. But the good points are it is (in most part) very realistic and the actors are superb. Yoo Ah In was great as usual (couldn't give enough praise for this actor) and Park Shin Hye did her part well (though I think drama suits her better than suspense). I guess the story line was just lacking in a lot of parts. But it's still better than most zombie movies out there.
