the Tenth doctor start life with a bang and keep on go . alien invasion during Christmas , werewolve come after the Queen , clockwork robot in France , Cybermen , Daleks , Satan and lot of comedy . this doctor , David Tennant , have a new style but just as much energy as the past doctor . he be both a man of action but also have a strong sense of ethic and belief that guide he even when all seem lose . all the episode have commentary , the dvd have lot of outtake , delete scene and special . a must for all Dr. who fan .
