 Writing in The Daily Telegraph, Christopher Howse, a commentator on religious issues, was critical of the documentary, awarding it two stars out of five and labelling it "disjointed". He argued that it placed too much emphasis on historiography but that its "crowning annoyance" was Holland's habit of pausing mid-sentence. In contrast, Ed West, also of The Daily Telegraph, praised the documentary, stating that it was "atmospheric and intelligent". Noting it would make many viewers uncomfortable, he argued that the Islamic world had to accept "higher criticism" and "embrace the pain of doubt" in order to improve life for themselves and for their non-Muslim neighbours.
