The Radar read

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

Synopsis

A reluctant bride-to-be is stalked by a serial killer who only kills brides and the people around them. While her friends get whacked one by one, a hard-boiled renegade cop whose bride had been killed years before tries to hunt the killer down before it is too late.

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.
