The What Not To Wear sequence goes on just that little bit too long after the revelation that the robots are equipped with some nasty machinery but it, too, is a touch of dark comedy before we reach the Game Station.

Once out of the game, the Doctor seems to know without being told that it’s exactly a hundred years since his first visit. How does he know? Does his sonic screwdriver – a all-powerful Swiss Army knife now – tell him? Lynda seems to know her way around the station which is also a bit odd. But the revelation that the current state of humanity is a result of the Doctor’s acts in The Long Game is great. It is almost redundant to say that Eccleston’s Doctor has real emotion throughout.

Back in Weakest Link and Rodrick appears to give “Hazel Dean” as an answer… When Rose loses (and here the line from the trailer – “Rose, you leave this life with nothing” – is omitted) and is disintegrated, it’s shocking and moving. Suddenly you’re not sure if she really is coming back or if this is one of the terrible, unexpected twists and Lynda is the new companion.

The Doctor, Lynda and Jack are threatened with the lunar penal colony (see Frontier in Space with its similar ending) before they reach floor 500. At which point for the second week running the TARDIS provides a leap in the plot, sapping a little of the drama. Hopefully the final episode will reveal just why the Daleks are teleporting game losers. That evicted Big Brother contestants don’t actually die takes the edge off the satire a little.

The Controller (see Day of the Daleks) looks terrific and when she arrives on the Dalek ship you see horrible holes in her flesh where she was connected to the Game Station systems. The revelation of the Dalek fleet and the incidentally music with it is very effective, as is the brief shot of a sucker approaching Rose (see The Daleks).
