I really enjoyed this one. Excellent premise with it being 10 million years in the future and the last humans are leaving Earth for a new planet. The Doc and co arrive and accidentally infect them with the common cold, which is deadly to them! It’s perfect sci-fi, really, with a great twist in the story half-way through, and not one episode felt wasted or dragged out.
The Monoid aliens are creepy (a single eye inside their ‘mouth’ under a mop of hair), and is it my imagination or did the BBC throw a shedload of money at this one, because the two main sets are pretty huge and extravagant too. The control room set is brilliant and full of little details and built-in TV screens and things.
The only bad thing I can say about it is that the new companion ‘Dodo’ has a terribly annoying voice, but I think that’s the point of her, since even the Doctor says he wants to teach her proper English.
That aside, I think this is my favourite Classic Who serial so far, and without even a mention of Daleks!
