6.1 ★Why we're confident in this score
988 ratings. The score is reasonably stable but could shift up to 0.10 as more ratings come in.
The Math
Prior (global mean)m = 5.985
Prior weightC = 500
Observed ratingsn = 988
Observed averageR = 6.23
Posterior mean (Bayesian score)6.145
95% confidence interval±0.0958
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.
