this be one of the best episode of doctor who ever . we have the cybermen and the cyber conversion unit ( may scare young child ) and of coarse the doctor do one of his best act . bravo david tennant . good scene a if it be a movie and with thrill scene in some street and an invasion on the cyberman base and and leave the world different to ours and basically a 45 minute movie . be part 2 of rise of the cybermen and this would never disappoint . with it have a great build up to the final . the doctor plus an evil enemy ( daleks and cybermen and master and sontarans and davros and autons and or even macra ) be a battle to the death and just be careful with young child watch this .
