Didn't have huuuge expectations, but surprisingly I quite enjoyed it. I liked it cuz it felt like a slice of life-ish zombie story, which I prefer rather than the 100% action ones (those aren't really my type). I feel like they portrayed how actual real life people would act if there was a sudden zombie apocalypse. I would be scared, not knowing what to do, 24/7 home alone, bored, even contemplating suicide, all of which these characters went through at some point.
I also liked the relationship between the two, it feels really sweet and sincere teamwork. Park Shin Hye really got better as an actress in this one. Yoo Ah In did a great job as always.
The ending was quite predictable (I already knew they were going to be rescued; it always happens in zombie films) but it was okay. I cared about them so I wanted them to survive.
So, if you want to watch a zombie film but are scared of too much blood, violence, etc. then this one may be for you.
8.5/10
