Cold War had an Appreciation Index, or AI score, of 84.
The Appreciation Index or AI is a measure of how much the audience enjoyed the programme. The score, out of a hundred, is compiled by a specially selected panel of around 5,000 people who go online and rate and comment on programmes.
The score is identical to last week's Doctor Who and scored higher than most of Saturday's output. The highest scoring programmes of the day were Casulty with 88, Walking Through History with 85 and Dad's Army with 89.
