for those of you who enjoy the new Doctor who , series 1 , you will not be disappoint with series 2 ! David Tennant take on the role of the Doctor , and do it with such finesse and charm you will be immediately suck in . Billie Piper continue she role as Rose Tyler for another season , and she farewell be truly heartbreaking . this season be full of fantastic adventure , bring in old foe such as the Cybermen and the Daleks , and introduce some new one . the doctor and Rose meet up with Queen Victoria , the Doctor 's old assistant Sarah Jane Smith -lrb- and k-9 ! -rrb- , and even take on the Prince of darkness himself . grant , there be one or two episode that I be not particularly fond of -lrb- i.e. `` fear she '' feel more like a pitch for the 2012 Olympics to be in London rather than a real episode -rrb- , but overall this be probably my favorite season so far -lrb- `` The Girl in the Fireplace '' be one of my all time favorite episode ! -rrb- . there be also hour of special feature , include David Tennant 's video diary which give a insightful look behind the scene . definitely a must have for any Doctor who fan , despite the price . it be well worth it , not to mention you would pay much more if you buy it anywhere else !
