Voyage of the Damned scored an Appreciation Index figure of 86 making it one of the most enjoyed programmes on British Television this Christmas. A score above 85 is considered excellent. It was the highest score on either of the main two channels for the day.
For a drama series with such a massive audience to score so well in the Audience Appreciation figures is very unusual and a real measure of just how well the show is performing. The only other programmes to score higher on Christmas day were "Romeo and Juliet" on BBC2 and "The African Queen" on Channel 4.
The Appreciation Index, or AI, is a measure of how much the audience liked the programme. It is a score out of 100, based on responses from a carefully selected panel. The average score for drama on BBC1 and ITV1 is 77. A score in excess of 85 is regarded as excellent while a score below 60 is poor.
