Strictly speaking, I suspect this series is pitched at late teens and twenty somethings. That said, Revenge of Others is quite accessible, to a range of viewers. Thankfully, it doesn't play heavily on the teenie aspect of the drama. Instead, this is essentially a crime thriller, with a social commentary, about rich vs poor. The story can get a little convoluted at times, you have to pay attention to the plot twists and turns. If you do, it does reward the viewer with an intriguing tale of revenge and murder. Acting is excellent and chemistry/rivalry between key protagonists, is convincing. In summary, a quality crime thriller from South Korea. The story is complex, so the viewer does need to pay attention but will be rewarded, for their efforts.
