adlvcolt I like this episode as one that tries to break new grounds in the established Doctor Who series, getting out of the comfort zone. Here we see the Doctor in another episode flying solo and how this affects his judgment without an opposite like Donna. The companion always challenges some critical decisions of the Doctor. The episode ending shows that and how this might affect his future. It is clear special effects and sets have improved a lot through seasons and this episode has a cinema film feeling in its execution. The enemy here is really scary and not always when visible. Acting is excellent and Mr Tennant shows very well Doctor's conflict at the end. Can't wait to watch next episode.

1stbrigade While "Doctor Who" has always had its share of fun, there have been times that it's taken a darker tone. "The Waters of Mars," the second of four specials that mark the end of David Tennant's time as the Tenth Doctor, is such an episode. It's a thrilling, funny, and downright creepy episode. And dare I say it, but I thought it was the darkest episode of the show's history. But not because of the creatures, which the Flood is a downright terrifying monster for the Doctor to face. And it's not the fact that the Doctor has landed at a fixed point in time where historical events must take place, meaning everybody on Mars' Bowie Base One will die. What makes this the darkest episode of all time is none other than the Doctor himself. After having witnessed so much death and destruction, including the death of his own people, the Time Lords, he takes a turn for the dark, believing that he has a right to change historical events, because he is the last of the Time Lords, and decides to take on time itself. He begins by rescuing the three humans not infected by the martian water, including Adelaide Brooke, the base's commander, and a hero. Through some truly ingenious work, he gets them back to Earth on the same day as their death. But now, the Doctor has taken on a dark and malicious arrogance, and believes that there is nothing he cannot do. But Brooke decides to make sure the time line stays right for her, and commits suicide. When she does this, the Doctor realizes that he has gone too far, and believes that his death is at hand. "The Waters of Mars" is definitely the best special created so far: an exciting, character-driven, dark adventure that takes on a more grim storyline that is more suited for "Torchwood," but works here. If there is a complaint I have, it's this, which is more an observation: This episode, with it's dark ending, is definitely not one for young children. But still, it's a terrific episode, and bodes well for the final two episodes of the David Tennant/Russell T. Davies era of "Doctor Who." Grade: A+

ktd-1 invisibleskidmark, you obviously did not watch the "Stolen Earth" or "Journey's End" closely because the Daleks in the Medusa Cascade were NOT part of the Time War.At the end of the "Evolution of the Daleks" (series 3) the last of the Cult of Skaro (Dalek Caan) did an emergency temporal shift which SENT HIM BACK INTO THE TIME WAR where he consequently rescued Davros, creator of the Daleks, and lost his mind (went mad) in the ensuing ability to see all of time and space. The Time War was timelocked and Caan somehow broke through it. The incident at the Medusa Cascade happened and lost planets returned to their appropriate places and times. It became a FIXED point in time/space.There was no continuity problem regarding the Medusa Cascade incident as we saw that the whole of Earth was celebrating the return of Earth to the Solar system in "Journey's End" I suggest before commenting on continuity that you remove the finger off the fast forward button....

Matthew Kresal Once in a while your favorite TV series will surprise you. I remember liking but not being blown away by The Next Doctor and being utterly disappointed by Planet Of The Dead. So I wasn't sure what to make of the next special Waters Of Mars, especially with it seemingly delayed to the point of being an afterthought to what promises to be an epic finale to the tenth Doctor era. So imagine my surprise upon finally seeing Waters Of Mars and discovering that not only was it a major improvement over the two previous specials but that here was a story featuring everything that makes Doctor Who great was in it: action, fine acting, horror and yet it being a personal tale at the same time.David Tennant turns in his best performance since Human Nature/Family Of Blood. Here we see a tenth Doctor like we have never seen before on a roller coaster ride of emotions. We first see a Doctor thrilled by adventure as he always has before realizing he's in the wrong place at the wrong time and trying futilely to not get involved. Then we see something unexpected during an incredible eleven or twelves minutes with a Doctor who throws caution to the wind and soon learns the price of doing so. Tennant's performance throughout all this is nothing short of one word: extraordinary. It's a performance that hits all the acting notes beautifully and may well be Tennant's best performance in the role.There's also a fine supporting cast as well. Lindsay Duncan plays base commander Adelaide Brooke, who in a way becomes a one-off companion of sorts. Yet she is far more then just that though. In just an hour she becomes a full fledged character with a back-story and a character arc as well. Brooke is a pioneer who finds herself caught up in a crisis with a man who knows what is about to happen and, in the end, will be utterly appalled by the actions he will take. Duncan plays the role well as she shares some fine scenes with Tennant during the back half of the special, especially during one of the most emotional scenes the New Series has yet served to its audience. Duncan was a perfect choice for the role and her presence helps to elevate the special's quality. There's also a good supporting cast as well in the form of base members including Peter O'Brien as Ed, Alan Ruscoe as Andy, Sharon Duncan Brewster as Maggie and Gemma Chan as Mia Bennett. Together they make a fine supporting cast.There's also some fine work behind the camera as well. There is some fantastic make-up and effects work in regards to the villains of the special which make them, next to the stone angels from Blink, perhaps the scariest thing to have been used in the New Series, especially in the revealing of the first one which made he jump out of my seat (literally). The base is well realized both in the form of the sets interiors (including some fine location work) and the well done CGI exterior as well. There's also a really well done version of the Martian surface as well which is almost convincing, especially with the Doctor walking on it. Then there's the robot Gadget as well which is almost a character rather then a prop. Plus there's the music of Murray Gold that, especially in the last eleven or twelve minutes, shows once again the power of a Doctor Who score. To top it all off there's the ever fantastic direction of Graeme Harper who once again proves himself to be the best director on the New Series by walking the tightrope of action, emotion, horror and suspense without ever falling off. Fine work by all indeed.Which brings us to the script. While Russel T. Davies previous collaboration with Gareth Roberts turned out to be something of a dud, his collaboration with Phil Ford proves to be among the better scripts of the New Series. Waters Of Mars takes the classic Doctor Who formula of base under siege and feeds into that formula action sequences, horror, sacrifices and the question at the heart of any time travel series: if you knew what was to happen and could change it, should you? It is that last question that occupies the Doctor throughout the special and that ultimately leads to a powerful finale that answers that question all too painfully. The script does what any great Doctor Who story should do: be exciting, horrifying and yet personal.Waters Of Mars qualifies as one of the finest stories of the New Series. It starts with fine performances from David Tennant, Lindsay Duncan and the supporting cast. It continues on into the production values including make-up, special effects, the CGI rendering of the base, the score and more of the fantastic direction of Graeme Harper. Then there's the script from Russel T. Davies and Phil Ford that hits all the right notes of action, horror, suspense and yet remaining a personal tale as well. Waters Of Mars ranks with Human Nature/Family Of Blood, Blink and Dalek as amongst the best stories to come out of the New Series and is a fine example of what Doctor Who is at its best.
