If you want a crime drama that treats its mystery as more than a puzzle, Who Are You: School 2015 is available in Australia on Netflix, and in the US on Rakuten Viki and OnDemandKorea right now. A single, tightly-focused season means there is plenty to get through without ever feeling padded. An 8/10 rating says what the writing already makes obvious: this one works. Kim So-hyun's performance alone is worth the time investment. Put it on tonight on Netflix and see for yourself.

There is a reason Who Are You: School 2015 keeps coming up in conversation. Who Are You: School 2015 treats its mystery as a means, not an end in itself. After losing her memory in an accident, a bullied high school orphan finds herself in the place of an identical-looking girl who's gone missing. The writing gets a boost from Kim So-hyun and Nam Joo-hyuk, who sell every scene they're in. It was aired in 2015. Who Are You: School 2015 is at its best in the quiet scenes between the plot beats, where the character work actually happens. It rarely drops the ball, and when it does, it recovers fast.

Viewers who think they have seen every crime drama tend to find Who Are You: School 2015 proves them wrong. Fans of Nancy Drew will recognise the sensibility here immediately. Short enough to finish in a weekend, substantial enough to feel satisfying. Kim So-hyun carries scenes that would sink a lesser production. The resolution feels inevitable rather than arbitrary, which is rarer than it sounds.
