How this number was made. We read every review and derive a 0–100 reading from each — including where the critic printed a number, which stays first on its row, because it’s theirs. The Filmi Score is the mean of 5 readings; 3 of those rows also carry the critic’s own rating, shown beside ours. 1 review carried nothing usable and could not move the score. Rubric v2, computed 7 Sep 2026. Any critic can ask us to remove a derived reading.

What readers say
The Audience Score appears once three readers’ reviews have been read under the rubric — built from what people write, never from the rating numbers.
