It’s so well done here that you can’t help but scan the Radio Times to see if, by some miracle, the next episode is on tomorrow

We don't buy what the Radio Times is saying, that it's the scariest Doctor Who episode ever. But we do think that it's one of the very darkest

A more heartwarming and life-affirming small screen half hour (or so) you are not likely to find this year

You'll see the Doctor and Sarah Jane combine forces to battle against their greatest enemy yet!
