A middle-of-the-pack signal worth a look, though the rating rests on a thin sample, so treat it as provisional.

Synopsis

High school student 'Ji-eun' was the victim of the crime, but distorted online posts and malicious comments made her into the perpetrator in the public eye, driving her to take her own life. Her sister 'So-eun' finds detective 'Jun-kyung' to uncover the truth behind her sister's unfair death, and he begins hunting down a suspect in cyberspace. As clues are revealed one by one, the case grows from a simple rumor into a complex web of truth involving anonymous accounts.

Radar blends quality, momentum and freshness into one “what to watch now” number — so a great older film can sit lower than a rising new release. The Quality signal above is the time-neutral rating, which is why an acclaimed classic keeps a high quality score even when its Radar number is lower. Radar outputs are editorial algorithmic recommendations, not objective facts, and may change as signals update. A Radar score is not the same as a TMDB, IMDb or critic rating.
