I be thrill when the new Dr who series come to the USA . Christopher Eccelston 's characterization of the doctor during the first season be more than I could have hope for . so I be very disappointed when he choose not to do a second series . then when I hear that `` Barty Crouch Jr '' from Harry Potter be step into the role well I be resign to never watch the good doctor again . to say that I be surprise with how much I like Tennant 's take on the doctor would be a understatement . he bring he own brand of quirky joie d vivre to the role that both fit and be different from Eccelston 's Doctor he characterization have a harder edge - he be willing to take a bit more violent stand and he be willing to let he feeling for Rose show a bit more the end of the second series really point out the tragedy of be the doctor -lrb- immortality be not all it be crack up to be -rrb- . I be glad Tennant be come back for season 3 . it will be very interesting to see what new character pop up since several from last season have go on to have spin off show in the UK . if you be a old time Dr who fan , like british tv , or be in to sci fi , you will enjoy this new incarnation of the old favorite .
