How lists are ranked

The About page says every list is built from TMDB ratings, vote counts, genres, runtimes and synopses, ranked by those numbers and not by a critic's taste. Streaming availability carries a date.

What JustWatch says about itself

Its About page says it shows where to legally watch movies and TV shows, with filters and tracking, and notifies users when a title reaches one of their services.

What this means for you

A pick is only as current as its source. Streaming rotates, so the date on the page matters more than the rating. Two apps using the same sources can still suggest different titles, because the choosing logic is separate from the data.

FAQ

Does What2Watch AI use critics' reviews?

The About page says its ratings are TMDB averages, with no star ratings of its own.

Is TMDB official?

TMDB is a database. What2Watch AI states it is not endorsed or certified by TMDB.
