    A creature in the ice, a small fly in the ointment but a Doctor on top form.

    The third episode of series 10 sees the Doctor and new companion Bill arriving at the last great frost fair on the River Thames, London in 1814. There are strange things lurking under the ice and a very unpleasant person manipulating events above the ice. The Doctor steps in to try to resolve matters.

    There are many excellent features to this episode and overall it is very good and enjoyable. Following on from a superb first episode and an ok second episode, series 10 continues to satisfy overall in terms of varied story lines, good scripts, strong character development, quality acting and entertainment.

    Capaldi as the Doctor is brilliant and executes everything perfectly in this episode including a powerful speech to the villain which is superb. Indeed there is a lot of powerful stuff in the script with Bill questioning the Doctor's morals, purpose, and way of life (as other companions have periodically since the very start in 1963 when Ian and Barbara challenge the Doctor's morals). The way it is dealt with here is very good indeed and reinforces the character of the Doctor as a man who has to make difficult choices and take difficult actions for the greater good. Steven Moffatt often overplays the darker side of the Doctor and hypes it up a bit in my opinion but writer Sarah Dollard here gets it just right. It questions him but shows that he definitely is making the tough choices for the right reasons.

    Issues of racism and how black people were treated in the past are raised and again are dealt with very well. Bill is establishing herself as a fine companion. Well acted and very likable, doing all the things a companion should. She is strong and full of personality but is not overly dominant or over confident in an annoying way.

    There are a couple of small negatives, I think:

    There is a slight lapse in internal logic/continuity when the Doctor and Bill go under the ice into the Thames in old fashioned diving suits. In real life these suits were exceptionally heavy and required an oxygen line for someone to remain underwater. It seems a little bit odd that in this they are able to move in the suits with relative ease and the means of providing air for them to breathe is not clearly used properly. But the thing that drew my attention more was when they emerge from the water and the suits are dry. This is not a major issue in the story at all but it is a silly and unnecessary flawed moment which took me out of it for a minute.

    Also, I feel the effects of the giant fish and of the attacks through the ice are not as good as they could have been.

    The fish story is not exactly the most amazing or convincing idea. However, it is interesting to have an unknown earth creature rather than an alien so it has some value in adding variety.

    This was a mostly really well written and performed episode.

    The regency time period is interesting and the setting is very nice to look at in terms of costume and the iced over River Thames with an atmospheric situation that adds to the feel of the episode.

    The villain is suitably horrible and the story is very solid with great moral aspects to the script adding intelligence to the relatively simple plot. That is the what we need from solid Doctor Who and Series 10 is nearly all solid Doctor Who.

    My Rating: 8/10.

    Series 10 Episode Ranking: 9th out of 14.

    Fantastic character development

    As an adventure I thought it was a pretty decent story, loved the Thames setting, loved the almost early classic series vibe about it, the whole linking random historical events to the show, and given a sci-fi explanation. The visuals were great, really impressive, zany in a way, the circus, the elephant, stalls etc. I love the concept of something menacing lurking under The Thames.

    Bill's reality check was the highlight of the show, I thought that conversation she had with The Doctor was fantastically well done, she's showing an emotional presence that hasn't existed in a companion I'd argue since Donna, Bill is truly proving to be the real deal.

    I wasn't blown away by the character of Lord Sutcliffe, I am a fan of Nicholas Burns, the character wasn't given any time to make any sort of impact. Nicholas Burns is about as villainous as a Labrador puppy.

    I loved the ending, I desperately want to know what exactly is behind the doors, could it be the Mondasian Cybermen?

    Next week's looks a cracker.

    Liked this one 8/10

    Doby Mick...

    You have to feel for poor Bill Potts, she's not been gifted the greatest plots. Doby Mick under the Thames, and parasite fish with glowing stems. Nanobots with a thirst for flesh, and water girls that don't refresh. Whatever next, a haunted house, possessed by Abzorbaloff parasitic space louse!

    Thin Ice

    The Doctor and Bill have landed in Regency London during the last great frost fair on the Thames.

    Bill enquires about the ramifications of treading in the past but when a little street urchin falls inside the icy river and devoured by an underwater chained up beast which excretes some kind of explosive poo, the Doctor only cares about retrieving his sonic screwdriver from the child's hand before the lad plunges completely into the water.

    An appalled Bill asks how many people has the Doctor seen being killed. We know the it is in the millions. The Doctor answers 'I don't know,' 'I care but I move on.'

    Bill then asks the Doctor if he has ever killed someone. Again we know the answer, millions. The Doctor is still reluctant to answer, we know why he always moves on so he does not have to look back.

    Lord Sutcliffe was the hissable villain of the week, he had no empathy for his fellow man and his racism led to a punch in the face from the Doctor.

    Sutcliffe also controls the beast for his own ends, although the story was simple, the early part of the episode was just a bit slow to get going. The production values and photography though were top notch. Mist was craftily used to cover up the limitations of the sets, for interiors, canvas and tents were deployed and the underwater sequence with CGI were rather niftily done.

    2 in a row

    While a little bit more exiting than last weeks episode, this still had the same form in the rushed ending. The bit about being black in 1800's England was done way better with 10th Doctor and Martha in the Shakespearean era, but I guess they have to repeat themselves nearly word from word every now and then?

    • Quotes

      The Doctor: Human progress isn't measured by industry. It's measured by the value you place on a life... an unimportant life... a life without privilege. The boy who died on the river, that boy's value is your value. That's what defines an age. That's... what defines a species.

      Lord Sutcliffe: [moved] What a beautiful speech. The... rhythm and- and vocabulary are quite outstanding. It's enough to move anyone with an ounce of compassion.

      Lord Sutcliffe: [sternly] So it's really not your day, is it?
