Happiness 9/10 - 2021
plot - disease which makes people mad wanting to drink blood of noninfected appears. This drama is story about infected closed in one place. And military trying to stop spreading of disease + looking for cure

even though its not zombie drama its alot alike one only difference. Zombie states turns on and off by time. Will rate this drama like it was zombie one.

In such case its peak drama. Second good zombie type movie I have seen from koreans right after Train to Busan 1.

Even though this drama happens mostly in one skyscraper it can be quite chaotic since at each floor is always something happening and camera goes from place to place.
Action, Thriller, Love story, zombie type all in one.
