David Tennant pick up where Christopher Eccleston leave off without miss a beat . as the 10th and newest doctor , Tennant 's quirky Doc be refreshing and just funny enough to pull it off . he chemistry with Billie Piper , who play Rose Tyler , be fantastic as the drama intensify to a sad finale between the doctor and Rose . I recommend season 2 as a great buy and the additional extra on the dvd 's be fun to watch with all the behind scene , personal video diary and commentary . enjoy !
