It's become my second favourite from this strong season. Only being two parts, it breezes by. The Doctor, Sarah and Harry all get something to do, and the Sontaran, played by the same actor from Time Warrior, is once again great as a member of this species.

Yeah don't worry about the human side characters, or that Sontaran invasion fleet, the Doctor has Genesis of the Daleks to get to! greenLetterT View profile Like Liked 0 24 April 2025 · 31 words Review by Azurillkirby Sontarans are cool! ...I don't have much else to say. The story is perfectly good, but at only two episodes, there's not much of substance to dig your teeth in. B.

This is my LOTR helmet kick scene. Nitronine View profile Like Liked 0 Show All Reviews (15) Open in new window Statistics AVG.
