Doctor Who: Blink
by Steven Moffat; dir. Hettie Macdonald (BBC, 2007)
No ‘Doctor-lite’ episode should work this well, but Moffat’s script offers an adroit balance of humour, suspense and timey-wimey SF, the Weeping Angels are creepily effective (at least as a one-off), and Carey Mulligan, taking the lead, puts in a virtuoso performance.
