Carey Mulligan carries the whole episode; it's the scariest one of the new series, the introduction of a fascinating new villain and a brilliant use of time travel. A modern classic, even more impressive that the Doctor's barely in it.
4. The Doctor's Wife
Possibly the greatest idea anyone's ever had for a Doctor Who episode, Neil Gaiman gives the TARDIS a voice and a body; she's wonderfully eloquent, philosophical and eccentric, and there's a chemistry between Suranne Jones and Matt Smith that typifies 49 years of the show.
3. Vincent And The Doctor
Easily the best historical figure episode, 'Vincent and the Doctor' is a moving study of a man considered to be mad, his mental illness and how it feels to be loved. It's a magnificent episode that uses everything great about Doctor Who, to soar to phenomenal heights.
2. Human Nature / The Family Of Blood
The central conflict of the show has always been the Doctor, torn between his alien side and Earth, of his power and mercy, of his companions and of enemies. This is a story that examines all of this beautifully, touching on the Doctor's role in wartime, and delivering it with superlative acting and an exceptional script. Tennant's finest moment as the Doctor.
1. The Empty Child / The Doctor Dances
Maybe a controversial choice for number one, but Steven Moffat's first Doctor Who story is still his best. It's a tale that enforces the power of love, and it's the moment that the Doctor found his confidence. It's brilliantly written, from the terrifying moments to the satisfying ones, and that conclusion is easily the best of the revival.
