Basic premise: How to survive a lockdown with zombies in an apartment building. Key tip? A baseball bat, Park Hyung Sik and Han Hyo Joo. With these three, your survival rate will be 95% unless you have an alliance with one of the other tenants in the building. If that is the case, your chances of surviving the lockdown will be much lower.

Unlike a typical zombie-themed drama, this show is light on zombies running around looking for the next meal. Instead, it focussed on how to survive a lockdown with no power, no internet, with an added scarcity of food and water. Oh, and how to keep zombies out of your apartment.

Happiness' cast list is the who’s who of the Korean entertainment industry. We have PHS and HHJ as the leads, and they are smokin’ together. However, the supporting cast, I think, were the true stars of this show. They were over-the-top and delivered some of the best audacious lines someone can safely utter in a dramaland. So much so, PHS and HHJ are merely policing their outrageous behaviours.

Lastly, the building used in Happiness deserves mention. The apartments where the characters lived are a nice extension of who they are. However, the old university dormitory sends shivers down my spine. It is old and decrepit where I feel like having a shower when that location appears on my screen.

Happiness is one of the enjoyable dramas I have watched this year, and the length of episodes is apt.
