The Deadly Little Mermaid (2026)
The Radar read
A middle-of-the-pack signal worth a look, though the rating rests on a thin sample, so treat it as provisional.
Synopsis
Some secrets are better left at the bottom of the ocean. Once she's in your house, there is no escape. When a struggling artist pulls a beautiful, unconscious woman from the freezing coastal waters, he thinks he’s performed a miracle. But as she recovers within the walls of his secluded home, a series of unsettling events leads him to a terrifying realization: her presence is no coincidence. She is inextricably linked to the same watery grave that claimed his family years ago.

Open Double Feature RadarRadar 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.
