Methodology

The Balasaur Score is a 0 to 100 blend of ratings from IMDb, Rotten Tomatoes, Metacritic, and TMDB. When a source has no rating for a title, the remaining sources are renormalized so the scale still runs 0 to 100. These are the weights.

TMDB carries the smallest weight because it is an audience score with looser standards than the others. It is also on nearly every title, which is why a card can almost always show one score instead of falling back to a raw star rating.

A worked example. Inception holds 8.8 on IMDb, 87 on Rotten Tomatoes, 74 on Metacritic and 8.4 on TMDB. The two ten-point scales become 88 and 84, then (88 times 0.25 plus 87 times 0.125 plus 74 times 0.125 plus 84 times 0.10) divided by 0.60 gives 84.

A collection only makes the cut when enough qualifying titles exist. A qualifying title must have a poster, synopsis, score, and no flagged content.

Membership in a ranked list favors titles with many ratings, utilizing a Bayesian vote confidence adjustment. Display order within the collection is strictly determined by the Balasaur Score.

A list ends where its quality falls off. Every collection keeps at least its top 12, no title makes the page scoring more than 25 points behind that collection's leader, and no list runs past 60. Strong shelves run long, thin shelves stop short.

Titles refresh from TMDB and OMDb on a nightly sync that works through the catalog oldest first, so every title is re-checked on a rolling cycle. Every collection is rebuilt nightly to ensure rankings reflect the latest data. Each collection page displays its own rebuild date.
