tvN's apocalyptic thriller Happiness (해피니스) is terrifying simply because it hits so close to home in 2021. Set in the very near future where infectious diseases have become the norm, Happiness grabs hold of some familiar narrative themes and blends them together with frighteningly relatable real world situations. As much a character piece as it is a horror-tinged thriller, Happiness makes use of a strong cast, creative direction and the stoking of real world tension for what may be the last great series of the year.
