 IGN's Travis Fickett gave the episode 9.1 out of 10, praising the way the audience felt they had known Sally Sparrow for a while, as well as the strength of Mulligan's performance, although he noted that "all of the performances in this episode are exceptional".He concluded that, "it's difficult to believe that so much was accomplished in such a short amount of time.The story of not one, but two relationships was told, several time lines intersected and a new and rather frightening enemy was vanquished without The Doctor ever coming face to face with them".
