How is the fan score worked out?

It is a Fair Score, not a plain average. Votes from brand new accounts, accounts that have rated only one film, several votes from one network, sudden bursts, and accounts that only ever give 1 or 5 stars count for less. A few early ratings cannot swing it. Nothing is hidden: we show the star bars above.
