To be honest, I picked watching Happiness because both of the main actor, Park Hyung Shik and Han Hyo Joo. They have a great acting and I enjoy their past work. Though, I couldn't help but got disappointed by the stories and the character building this drama has.

Happiness actually has a good unique premise. It is a zombie themed drama that pour slice of life scenarios into it. It has a great opening that is linked to our current pandemic situation. This drama started by how people overcome and get used to the virus and continued on their daily life. But, a good premise need a good execution.

A story need a character to let it flow. What disappointed me the most, how poor written the characters are. Happiness has two main lead that is a former highschool mates. Both Sae Bom and Yi Hyun are shown as a strong selfless characters with no weakness. Is it wrong for them to act like that? Of course not. But as a viewer, we never get a glimpse of understanding on how both the leads grow into the person they are. There is no introduction of their past and they just suddenly show both leads as a cool detective and officer. I actually expect the drama to give background stories for the leads even if for a bit so there can be a character development and we can connect to the character growth, but nothing until the last episode.

This goes for the supporting roles as well. Each resident have different background and that can be a great foundation for the stories. But again, there is no a scene of process of building the character with depth and they are shown as frustated selfish characters just because they are trapped in quarantine. They give us a poor written villain over other poor written villain over other else poor written villain and stuck them up in one place.

How about the apocalypse setting? At first I am truly interested with the setting and I actually link the virus outbreak in the drama with the title of 'Happiness'. I thought the 'Happiness' emotion might be related on how the infected could bear the virus, but again there is no explanation. They don't give any scenes about the virus, the illegal drug, or even the symptoms.

In fact, Happiness actually casted many great actor and actress that played well with the acting that can make you stay to watch and that is my reason to finish this series. But, there is a lot of scene that against the flow of logic established by the story's plot. If you are not bothered by illogical, unlikely or impossible events, you can begin watching this drama.
