I watched it, and I was thrilled. It was a fantastic episode, and the Silence are fantastic aliens – they’re not Weeping Angels, but their concept is better than the Vashta Nerada, Moffat’s other big creation. Stephen Moffat is a superb writer, and he delivered a superb, funny, terrifying, and thought-provoking episode; I can’t wait to see part two! “The Impossible Astronaut” ended on quite a cliffhanger…
