Somehow there are still Cybermen in the parallel Earth. Jackie, Rose and the Doc go and help Mickey and Rose's parallel dad defeat them with optional location filming in Paris if budget allows. Rose decides she's had enough gadding about the universe and opts to stay on parallel Earth with Mickey. ...
Not a bad little story, but more of a snack than anything substantial. Is anyone old enough to remember ATV's Escape Into Night (aka Marianne Dreams, aka Paperhouse) .... reminded me of that a little.
I'm not suggesting that every episode of Who should be like this but when I said in an earlier post that I'd like to see the show try something a bit different and a bit riskier every now and then, this was the sort of thing I had in mind.
I agree with Adam. It's nowhere near the abomination some of you are making out, in fact it was a quite refreshing episode. It's nice to see the programme trying something a bit different for a change. If every episode is going to be spaceships and running down corridors then it'll soon get as stale...
