The Radar read

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

Synopsis

Frédéric Lansac, an artist and botanist, has a wild affair with party girl Moira, but throws her over when he meets the lovely Anne. Frédéric and Anne marry, but tragedy strikes when Moira shows up at the wedding party and makes a scene, causing Anne to fall into a bonfire. Frédéric and Anne lock themselves up in his mansion with his servants, a pair of mute dwarves. Anne, needless to say, becomes bitter and demanding. Frédéric tells everyone Anne has died, then on the sly, hires a nurse to look after her.

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.
