Doctor Who: The Waters of Mars

Doctor Who: The Waters of Mars is a one-off special episode from the acclaimed British science fiction television series Doctor Who. Produced by BBC and originally aired on BBC America in 2009, this installment marks the second of five specials that were broadcast between the fourth and fifth seasons of the revamped series which started in 2005. This particular episode prominently features David Tennant in his iconic role as the Tenth Doctor. It is penned by Russell T. Davies and Phil Ford, and directed by Graeme Harper.

The “The Waters of Mars” storyline thrives on the unique stand-alone nature of its narrative, incorporating key elements that hallmark the Doctor Who series - time travel, alien encounters, high-stakes dilemmas, and above all, the charmingly eccentric character of the Doctor himself. Set on the fateful day of November 21, 2059, the episode unfolds on Mars where the Doctor finds himself on a human-built outpost known as Bowie Base One.

At the helm of Bowie Base One is the determined and highly capable Captain Adelaide Brooke, played by British actress Lindsay Duncan. She brilliantly delivers a strong, complex character that cements her place in the pantheon of memorable one-off characters in the Doctor Who universe. The episode deftly uses the isolating Martian setting and the interpersonal dynamics of the human settlement crew for dramatic tension. If you love a blend of tension, crisis, high-concept science fiction, and heart, this special episode will not disappoint.

The mystery of The Waters of Mars involves a terrifying transformation that threatens the lives of the outpost crew and represents an unprecedented, deadly threat. Sharing a similar atmosphere to Hollywood's Mars-themed movies like Ridley Scott's 'The Martian' and Brian De Palma's 'Mission to Mars,' “The Waters of Mars” explores the harsh realities and acute dangers of extraterrestrial exploration. Still, it maintains its intrinsic Doctor Who elements of suspenseful plot twists, riveting emotional challenges, and intense action sequences.

What distinguishes “The Waters of Mars” even further is its thematic interrogation into the 'rules' of time travel and its dilemmas of interference vs non-interference. It puts the Doctor in a morally tough predicament, grappling with his responsibilities as a time traveler against his impulse to aid those in dire need. Through these series of events, viewers get to experience the Doctor's conflict firsthand, adding an additional layer of depth to the enigmatic Time Lord's character.

Visually, the episode is a stunner, with the Martian environment convincingly portrayed through top-notch set designs and visual effects. The cinematography and special effects team have managed to fully render a Mars outpost, which highlights the show’s ability to produce movie-styled narratives within a television format. The suspenseful and moving score by Murray Gold also adds to the richness of the episode, providing an impactful audial backdrop to the unfolding on-screen drama.
