The Radar read

A quieter title still finding its audience, though the rating rests on a thin sample, so treat it as provisional.

Synopsis

Blue Cocoon follows the story of Cynthia, a woman who lives alone, isolated from the outside world. Her day-to-day routine involves listening to an old grammar phone and the catching and killing of butterflies in vicious traps that hang from her window. One day, this routine is disrupted as a curious young girl enters her garden unexpectedly. Cynthia is besotted by the girls’ grace, youth and beauty and in her deranged, intoxicated state, decides to kidnap her using the chloroform that she uses on her butterflies, and on herself recreationally.

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.
