Writing for '' The Guardian '' , Dan Martin also heavily praised the episode , specifically the Doctor 's anti-war speech in the episode 's conclusion . He stated " This Doctor has never been written better , Capaldi has never channelled Tom Baker more , that sequence is cemented instantly as the ' Capaldi moment ' in clip shows for the rest of time " , and while he said that " It was a risky game to attempt the sort of contemporary allegory " that the episode did , he soon confirmed that the episode " knocked it out of the park " . Alasdair Wilkins of The A.V. Club also acclaimed the episode , awarding it a perfect " A " grade – the third of the season . He began his review by saying " The climax of ' The Zygon Inversion ' makes explicit something that the best anti-war Doctor Who stories have always understood . Depicting the madness of war does n’t require an epic scale . If anything , narrowing the focus to a single conflict or moral dilemma clarifies the essential futility of violent conflict " . He then closed his review by claiming " The simplicity of the setup allows this two-parter to be one of the show 's strongest ever statements against war , not because the Doctor is challenging us from on high to live up to his standard , but rather because he wants no one else to know his pain " . Den of Geek praised ″ The Zygon Inversion ″ as the best episode of the current series , and named it , ″ one of the best pieces of screen entertainment of the year , full stop . ″ The episode aired a week after the crash of Metrojet Flight 9268 in Egypt , and resulted in 31 complaints to the Office of Communications ( Ofcom ) because of the scene depicting a plane being shot down . Viewers argued that the scene was inappropriate in the aftermath of the crash , but Ofcom decided not to launch an investigation . The regulator concluded that " the science fiction nature of Doctor Who and the storyline created a sufficient distinction from recent events "
