 IGN reviewer Matt Risley rated the episode 9 out of 10 , saying it " maintained the thrills , chills and scalp @-@ scratching plot twists of " The Impossible Astronaut " , whilst somehow tweaking its predecessor 's thundering pace into 45 minutes of near @-@ perfectly plotted TV . " When comparing it to " The Impossible Astronaut " , he said it was " scarier , creepier ... and more action packed in every way ... [ and ] also managed to leave things on a suitably epic , mythos @-@ expanding note . " He concluded , " the show as a whole has a brand new energy , and we can 't wait to see where Who goes from here . "
