269 ratings. The score is reasonably stable but could shift up to 0.13 as more ratings come in.
The Math
Prior (global mean)m = 5.985
Prior weightC = 500
Observed ratingsn = 269
Observed averageR = 6.17
Posterior mean (Bayesian score)6.051
95% confidence interval±0.1338
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.
