after the astounding climax to the first season , I find it hard to believe that this strong debut would ever be top . the Christmas special blow those doubt apart , as well as set the tone -lrb- and some plotpoint -rrb- for the rest of the season . this episode be one of the most unusual in the show 's history , as the doctor be incommunicado for almost three-quarter of its run time . the payoff be huge , with the best debut of a doctor that I have ever see . there be so many great moment in those fifteen minute . see the doctor work out who he be . the swordfight . six word . Russell T. Davies really stamp he mark on the series with this episode . the succeed episode all , arguably , vary in quality depend on how high you standard be . the most annoying aspect be the inclusion of Torchwood - which on reflection be not as subtle as the ` bad Wolf ' meme from last season . for I , the standout be the perfect three episode run - tooth and claw -lrb- Russell T. Davies -rrb- , School Reunion -lrb- Toby Whithouse -rrb- and the absolutely superb and near-perfect Girl in the fireplace -lrb- from the brilliant Steven Moffat -rrb- . all , for I , perfect Doctor who episode and also great example of the different tone and theme that the series have explore throughout its long history . New series fan may be perturb that Rose get less to do this season . it be clear , in retrospect , that the focus be on create story for the new doctor . while Rose 's backstory run as a subplot in the background . in retrospect this be understandable , but be rather jarring on initial transmission . especially as Russell 's plan for this season be not entirely clear from the first few episode . the dvd extra be as great as ever . in addition to the Confidential Cut-Downs , there be also the dvd commentary . Dissapointingly , Steven Moffat do not get a turn this time round , although he do provide commentary in a podcast freely available on the BBC 's Dr who website . however Russell T. Davies do commentate on Tooth and Claw , and be wonderfully entertaining and informative . it be also incredibly please to see the new doctor - David Tennant - make a big contribution to the dvd as well . he contribute commentary to three episode -lrb- School Reunion , Idiots Lantern , Doomsday -rrb- . and also provide a whopping 85-minute video diary that cover the entire season . it be a suprisingly frank documentary , show David 's initial nervousness at both live up to the Legacy he so clearly idolise , and cope with the hectic schedule that seem to be the hallmark of this new series . big kudos to Tennant for provide such a generous look at what it take to be the very best in this fantastic series . in addition to be one of the best doctor 's ever , he be also a great Ambassador for the show . look back on it , the second series be much much better than the already strong first season . whether or not you enjoy it depend on whether or not you accept David Tennant as the doctor . and whether you can accept that this new series flatly refuse to conform to fan expectation of what a science fiction should be . this be Doctor who as big-budget Family Entertainment . in my case , the answer be a resounding yes . this second series have help in lay a strong foundation for what be undoubtedly the greatest run this much-loved series have ever have . if I could , I would give this 10 star out of 5 . more please !
