5.6 ★Why we're confident in this score
Only 167 ratings so far. The current score has wide uncertainty. Treat it as a preliminary signal.
The Math
Prior (global mean)m = 5.985
Prior weightC = 500
Observed ratingsn = 167
Observed averageR = 4.45
Posterior mean (Bayesian score)5.601
95% confidence interval±0.1517
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.
