the second series of Doctor who be much better then the first series . the acting of David Tennant really make the series so much better . also Billie Piper have grow in she acting skill and play well off of Tennant . here be my take on the episode rate with 4 be the best . the CHRISTMAS INVASION : the doctor be stick in bed most of the episode leave Rose to figure out how to stop a alien invasion . David Tennant play the doctor as if he always have be . \*\*\* NEW EARTH : the doctor take Rose to she first alien planet where and old enemy be wait for they . this be not my fav . episode but it do have some nice character moment . \*\* tooth and claw : the doctor and Rose find themselves in Scotland where they meet Queen Victoria , Evil Monks and a werewolf . Plotholes aside this be a very enjoyable episode . the special effect be some of the best i have see on the show . \*\*\* SCHOOL REUNION : the doctor investigate a school where strange thing be happen . this episode be very fun for two reason : the doctor meet some old friend -lrb- Sarah Jane Smith and K-9 !!! -rrb- also that jealousy that spark between Rose and Sarah Jane . also Anthony Stewart Head be great as the villian Mr. Finch . \*\*\* 1\/2 the girl in the fireplace : the doctor , Rose and Mickey arrive on a spaceship in the 54th century where they find timehole lead back to earth 's past . this episode be one of my top fav . \*\*\* 1\/2 rise of the cyberman : one of the Doctor 's greatest enemy be about to come to life on a parallel earth . this episode mark the return of the cyberman and Rose 's father . \*\*\* the age of STEEL : this episode be much darker then rise , but the dark atmoshpere add much to the story . also Mickey 's charater arc take a surprising turn . \*\*\* the idiot 's LANTERN : it be the 1950s and the coronation of the Queen just day away . people all over england be get turn into faceless zombie by they television . this be mostly a filler episode but with some fun bit . not my fav . but still enjoyable . the villian be also not that great . \*\* 1\/2 the impossible planet : the impossible have happen a planet orbit a blackhole . can the Doctor find out why before something deep within the planet awake ? this be a very fun episode and also a episode that not set on earth . \*\*\* 1\/2 the SATAN PIT : as Rose be threaten by the ood , the doctor face a anicent evil . this episode be a classic . \*\*\*\* love and monster : a ordinary man become obsess with the doctor and try to find he . this episode be not as bad as everyone say it be . the villian be dumb but the story show what happen to the people the doctor leave behind . \*\* 1\/2 fear her : another filler episode fill with some nice character bit . beware the giant scribble . \*\* army of ghost : Torchwood be reveal while the doctor be take prisoner . who be the Army of Ghosts ? Rose come into she own in this episode . a great episode . \*\*\*\* DOOMSDAY : as Torchwood and the world be invade , will the Doctor be able to save we ? a heartbreaking conclusion to a excellent season . a great episode with a somewhat offbeat cliffhanger . \*\*\*\*
