Doctor Who: A Town Called Mercy had an Appreciation Index or AI score of 85.
The score is a measure of how much the audience enjoyed the episode. It is based of a survey of 5000 people. The score of 85 is slightly lower than the first two episodes in the series, but still puts the programme into the excellent category.
Highest scorer on the two main channels was Casualty, with 88, while highest scorer of the day was Coast on BBC Two with 90.
The new series of Downton Abbey had an overnight rating of 9.0 million on Sunday night, which helped, along with Sunday's X Factor, push Doctor Who down to 16th for the week on overnight figures. Final consolidated ratings will be released next Monday.
