With the ghosts from Part one finally exposed to being a huge army of Cybermen and with the void ship opened to reveal the ever dreaded Daleks this episode has a lot going for it and it delivers. The cybermen have two immediate objectives (to upgrade humanity and to secure the 'void ship') while the Daleks seek to find out what these ghosts are and more importantly to activate the 'Genesis Ark'. The Doctor and Jackie are stuck with the robotic and numerous Cybermen while Rose and Mickey are stuck with the ingenious Daleks. What more or less happens is that the Cybermen and Daleks go to war because the Daleks class themselves superior and Humanity is stuck right in the center of it.
The acting in this episode as always is spot on and the story line moves fast and at a fitting pace. Surprisingly there is also enough space for humor in this episode as the discussions between the Cybermen and Daleks reveals. The Genesis Ark is also spectacular when its purpose is revealed and I really did get a chill down the back to witness the return of the black colored Dalek.
This episode simply blew me away on every level and ends much more emotional than you may imagine with a inter-robot war engaging and a very touching ending. Even today after Martha, Donna and Amy this episode stands out as a great achievement and its simply superb when so many elements come together so perfectly especially in Doctor Who and so well deserves a full 10.
