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

Open Double Feature RadarContent check
Based on the age rating and content tags — not a full scene-by-scene list.
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.
