The one where the Doctor blows up the Dominators' ship...
Surprise, surprise! Rago steps in to stop Toba's bloodthirsty threats, just like almost every other cliffhanger/ resolution in this sorry tale. Did the production team really think the young viewers of 1968 were that stupid? It's the same ending every week! Why would they keep coming back for more of the same? What a lacklustre way to launch a new season!
The one positive thing about this story, and particularly the last couple of episodes, is how strongly written Jamie is. Too often he's by the Doctor's side just to ask questions and be the light relief, but The Dominators shows him to be resourceful and determined, teaming up with Cully to blow up Quarks and cause as much disruption for the Dominators as possible. He's a man of action again, and it's great to see the character shine here.
