30,321 ratings, tightly clustered. This score is unlikely to move more than 0.02 with new ratings.
The Math
Prior (global mean)m = 5.985
Prior weightC = 500
Observed ratingsn = 30,321
Observed averageR = 8.72
Posterior mean (Bayesian score)8.676
95% confidence interval±0.0164
Formula: posterior_mean = (n / (n + C)) × R + (C / (n + C)) × m. The confidence interval narrows as more ratings come in. Films with few ratings are pulled toward the global mean.
