The Impossible Astronaut - Reaction

John Blunkett from the Guardian said: In truth the opening episode of the two-parter took a while to warm up, but a fiendishly complicated plot – it is probably not a spoiler to suggest it involves time-travelling – required no end of exposition. But by the end of the first episode it had drawn gasps and applause in almost equal measure from a preview audience at London's Olympia on Monday.Preaching to the converted in most part, no doubt, but this was scary stuff – almost as unnerving as those kids who kept asking for their mummy and the darkest series opener showrunner Steven Moffat could remember. And not a big-name celebrity guest star in sight.
