We are not worthy

This series of Doctor Who was a bit humdrum. Then came ‘Family of Blood’, which I thought was one of the best episodes ever. Next came ‘Blink’ – which has to be the best ever episode of Doctor Who ever; sheer televisual brilliance, like a great Diana Rigg-era episode of The Avengers. Only twice as good. This week I was finding ‘Utopia’ a bit humdrum again – and they pull another rabbit out of the hat – Derek Jacobi turns out to be The Master and regenerates himself into Life on Mars’s John Simm. Genius.
