Doctor Who Review - The Armageddon Factor

My review of the 103rd "Doctor Who" story, "The Armageddon factor," starring Tom Baker as the Fourth Doctor. "The Armageddon Factor" concludes Tom Baker's 5th season as the Doctor, aka the "Key To Time" season. It is also the final appearance of Mary Tamm as Romana, and the story also features the future Romana, Lalla Ward, in the role of Princess Astra. (1979)
