Netflix’s catalog is fluid; titles appear, disappear, and sometimes return with new licensing deals. Because of this volatility, any list of “good” horror movies must be anchored in criteria that remain relevant across catalogue changes—critical reception, audience engagement metrics, and thematic depth. By treating these criteria as independent signals, we can construct a reproducible assessment that works even as the library evolves.
Our approach also respects the limits of publicly available data. Streaming platforms rarely share exact view counts, so we rely on third‑party aggregators, critic aggregations, and user‑generated rating trends. These sources provide a reliable, albeit indirect, view of a film’s impact. Where gaps exist, we note the uncertainty rather than extrapolate unsupported conclusions.
