Things don't stay the same for long in the Whoniverse these days and there are several
interesting developments in this episode which is something of a game of two
halves. The first half follows the series’ conventional approach for contemporary
stories with a big threat, a supervillain, and some powerful visuals. Then
something happens during the second half wherein the story takes a bold right
turn that will no doubt irritate some fans. Then again we don’t want the
programme to be too predictable do we?
Spoilers aplenty after the break
