Plus side: Bernard Cribbins, aka Wilfred Mott aka Donna's grandfather, is as incredible as he was in "Turn Left" as is Jacqueline King, aka Sylvia Noble aka Donna's mother. They really bring the show back to it's first season in terms of believable, 'real' characters.
Just watched a preview of part 2 and had a thought.
The woman in white = the Doctor's wife?
That'd be awesome!!
