Frontier in Space - Episode 2

I'm becoming convinced that this story should have been called "Prison Cells in the Future" or something similar. In this episode alone, the Doctor and Jo are captured, put in a prison cell, taken to Earth, put in another prison cell, taken to see the President of Earth, taken back to their prison cell, taken from their prison cell, attacked and split up with the Doctor a prisoner of the Draconians and Jo back to their old prison cell, the Doctor escapes and is recaptured by the humans and put back in the prison cell with Jo, only to be attacked by Ogrons. Sheesh! And I know for a fact that more prison cells are in store for the remaining episodes. I do like the design of the Draconian ambassador's office. The buildings they filmed the location shoots at are quite futuristic, and fit the story well. Shame we see mostly prison cells, though.
