10 Best Doctor Who Episodes Written By Russell T Davies

If there was any doubt that David Tennant was the greatest actor to ever play The Doctor, then this episode surely extinguished any doubts. The transition from humorous, level headed but quirky time traveller to narcissistic, heartless show-off for our beloved Time Lord is brilliantly acted.

The writing is also wonderful for this epic adventure. Co-written with Phil Ford, this episode displays the strengths of Davies' concentration on character as the primary focus, while still utilising the sci-fi tropes that have made the show so iconic.

The action begins with Tennant's Doctor taken captive by the first human inhabitants on Mars. He soon realises that the crew are famous in Earth history, but not because of anything they achieved in life, but for the fact they will all die on Mars. The episode becomes a tug of war on The Doctor's emotions, aware that this is a fixed moment in time that he is not allowed to change, while also feeling obligated to save all on board.

Everything in this episode works to perfection, with first rate acting from Tennant, and a brilliant ensemble crew, backed up by a script with so many cards to play. The villains are a Modern Who classic, terrifying water infused creatures with a grand goal of taking over the Earth.

Then there's the ending, when all the pressure built up on The Doctor over all his years explodes on to screen. It is acting of the highest order bringing this phenomenal episode to its rightfully epic conclusion.
