Korea has no dearth of Zombie and post apocalyptic movies and dramas and sadly Happiness adds nothing new to the table.

There is nothing here that you probably wouldn't have seen in some shape or form already. It's the same old formula that has been repeated quite a few times.

Now there is nothing wrong with reusing well established tropes and using the same formula as long as you can make it work with a good storyline. But that's where Happiness falls short. It is riddled with plot holes so much so that after a point I just stopped counting them. Left and right all the characters keep making stupid decisions that makes absolutely no sense. And most of the side characters were so weakly developed and annoying that I could not care less about them. And to top it all off we have such an abrupt ending it makes you wonder if the writers just lost interest in the middle of it.

But where this drama falters in all other aspects, it makes up in terms of the two main characters. Especially Yoon Sae Bom, she felt like a breath of fresh air. Honestly I loved her, if not for her I probably would have dropped this.

And even though the romance between the leads was not the focal point there chemistry still knocked it out of the park. It was not too much in your face but they had a quiet domesticity between them that I absolutely adored.

It is however addicting to watch, it is the kind of drama that you binge watch at once and then forget it even existed because that's how low the impact was. Overall I'd say it's an oksyish one time watch.
