Kill It (킬잇) is a compelling example of a series that requires an upfront investment that will lead to a surprisingly emotional and satisfying conclusion. The 2019 OCN drama series starring Jang Ki Yong and Nana starts off with some intrigue before settling into a sort of oddly flat succession of disjointed stories. But that aforementioned investment and being able to stick with the series through to its almost abruptly exhilarating final minutes results in what ends up being a rewarding television experience.
