Saturday’s episode, Extremis, had an Audience Appreciation (AI) figure of 82.
The Appreciation Index in an indication of how much viewers enjoyed the episode, based on the reactions of a selected panel of viewers, who rate the episode shortly after transmission.
The score of 82 is considered to be good, though it is slightly below average for the Capaldi era and is one lower than last week’s score of 83. It’s in line with such episodes as The Girl Who Died and Listen – it is common for slightly more experimental instalments to get a lower AI.
