 Alan Stanley Blair of Airlock Alpha was positive in his review . In his opinion , the episode never failed to deliver and " acts as a tribute to everything Russell T Davies put in place when he resurrected the series in 2005 . " He described the storyline as " fast @-@ moving , bursting [ with ] excitement " and said that it contained " everything you would expect to see from an adventure comprising of all companions and a new Dalek empire " and " acts as the ultimate climax to four years of storytelling and will leave you with goose bumps for the full 42 minutes . " Blair was impressed about how Torchwood and Doctor Who crossed over when their original target demographics dictated it " should never have happened " , and commended scenes that depicted Gwen 's concern for her husband Rhys , Ianto watching The Paul O 'Grady Show , and Sarah 's and Jack 's emotional response to the Dalek transmission . Although his review was positive , he did criticise two parts of the episode : the concept of " time @-@ lock [ ing ] " the Time War was questioned because the Time Lords were annihilated in the conflict ; and he complained that the Doctor 's phone number was out of service .
