This series of Doctor Who is amazing from start to finish.
The opening episode The Christmas Invasion introduces the new doctor David Tennant. It starts a little slow but picks up well.
The start of the season proper is New Earth. This episode brings back the villain Cassandra from Series one's End of the World. The episode is highly entertaining with a truly emotional ending.
The following episode Tooth & Claw is when the series really heats up. Tooth & Claw set in 1879 sees the doctor and Rose meet Queen Victoria. The villain in this episode is a werewolf. This episode is truly scary and with a story that keeps your focus on the screen for the entire 45 minutes.
School Reunion brings back the much loved assistant Sarah Jane Smith with the also highly loved K-9. However, seeing these two characters return is not the only high-point of the episode. Anthony Head plays the alien headmaster of a school hoping to decode the laws of the universe to try and change it to benefit his species.
The Girl in the Fireplace is one of the best episodes of Doctor Who since the revival. A love story set in the future and the past with the doctor and a mysterious girl from the other side of a fire place become unexpectedly close after the Doctor saves her.
Rise of the Cyberman/Age of Steel sees the return of the Cybermen - a classic enemy from the old series. When trying to bring back old foes it can sometimes seem a bit forced, however here it is done professionally well. The cybermen are a scary enemy that will have you hiding behind the sofa :P
The idiots Lantern is a weaker episode of the series but still worth watching. Set in the 1950's for the coronation of Queen Elizabeth II. An alien gets inside the televisions and eats the souls of of people watching.
The impossible planet/Satin Pit is possibly the highest budget doctor who to date and the story does not disappoint. the doctor and rose land on a planet that is underneath a black hole but for a mysterious reason is not being sucked in. The crew of a space craft on the planet are drilling to the centre of the planet to discover what is down there to keep the planet safe. The doctor loses the TARDIS in a quake and is therefore stuck on the planet with them. What they discover down the pit is the biggest enemy of them all.
Love & Monsters is an episode that is either loved or hated. The episode doesn't focus on the doctor and rose but those of a cult group who wish trying to find out about the doctor. This episode is enjoyable if not looked upon too seriously.
In the episode Fear Her, it is evident that a low budget was used. Set in London at the time of the 2012 Olympics, children keep disappearing but no one knows why. It is up to the Doctor and Rose to discover the problem and save everyone that has gone missing. Not the best episode of the series but again worth watching.
The finale of the series - Army of Ghosts/Doomsday is a great episode. Bringing back the classic enemies Cybermen and Daleks. A war on Earth between three species. Humans, Daleks and Cybermen with a timelord fighting the human corner. Who will win the battle. See the emotional story of the end of Rose.
The series is brilliant, defiantly worth the price. Believe me, you will not regret the purchase of this 6 disc DVD.
