Spore Score: coming soon
We don't guess. Once Once Upon a Time in Harlem is out and The Pros (professional reviews) and The Punters (public ratings) have had their say, this page and the film page fill in the Spore Score automatically, usually within hours of the first reviews.
Trailer buzz
Buzz score 65 out of 100, which ranks it 20th of the 65 films we track releasing in the next three months. Trend: Steady. Its main trailer has about 454,591 views on YouTube.
In a sample of 50 trailer comments, 80% read as positive and 4% as negative (automatic sentiment check, run by us).
The Buzz score measures attention before release: how fast trailer views are growing (50%), total views (20%), likes and comments per view (15%) and comment mood (15%). It is not a review score and never feeds into the Spore Score.
