Anyone find it interesting that the Ood look strangely similar to the 'Great Cthulhu' of H P Lovecraft vintage? hmmm? Great pair of episodes (not referring to Billie Piper as most seem to do!) in The impossible Planet and The Satan Pit.Also the link to 'Legion' I think also used in Who before and also referring to Satan in various novels post Exorcist era...Great suspense episodes utilising fear and faith elements. The new team for these 'who's are working great magic for TV.This certainly creates new fears and 'hide behind the sofa' feelings not seen for many, many years in this continuation of a superb BBC series (pity it is confirmed by the BBC that Billie Piper is quitting - perhaps not permanently - after end of series 2) :O(((
