The Slitheen try to become lords of war.
17 January 2014 | by (Edinburgh.) – See all my reviews

The concluding part of the disappointing storyline that was developed by writer Russell T. Davies into the first two-parter of new Who, this episode improves ever so slightly on the previous instalment, but it doesn't do enough to be really enjoyable.

The devious plan hatched by the Slitheen starts to unfold. The Doctor, Rose and a woman named Harriet Jones (Penelope Wilton) are all trapped in a small room, but there's every chance that Mickey (Noel Clarke) could finally make himself very useful. Very useful indeed.

There's just too much here that seems too silly, with the Slitheen being perhaps the silliest. They pose a threat, but that threat is never really felt throughout the storyline.

Everyone on screen does well enough, with Annette Badland once more having fun as the villainous Margaret Blaine, but nothing works as it should, and the fun that everyone seems to be having fails to transfer to viewers.

Having said that, I can imagine that younger viewers will once again find this episode pitched just right for them.
