Yes, yesterday was indeed the day of the Doctor. It was the 50th anniversary from the broadcast of the first episode, thing that happened almost unnoticed because of John Fitzgerald Kennedy’s assasination one day before. But a hard start did not stoped the people from the BBC to produce episode after episode, and now, 5 decades later, to produce n episode about the first 3 years of the show and the first Doctor, William Hartnell. An adventure in time and space was broadcast Friday, 22th of November, and it can be describe in one single word: memorable. The British work made the idea to endure and to become a world wide phenomenon.
Last night BBC and some cinemas around the world broadcast the special episode the Day of the Doctor, an episode well done. The history from the Doctor Who Universe says that once there were a temporal war between the Time Lords and a race called the Daleks that burned everything in its way in the universe. The war ended in the moment the Doctor eliminated both rases along with his home planet, Gallifrey, into an attempt to save the rest of the Universe. To do that he stole a weapon called the Moment, something so powerful its operating system became sentient, and the Time Lords could not used it even in the last moments of the war, when the odd were against them. Who could use a weapon of mass destruction that could became his/her judge of the war crimes?
That moment was probably the worst moment in Doctor’s life, so bad that he overlooked or even forgot some things. The John Hurt’s incarnation was considered that Time Lord that betrayed the name of the Doctor.
The day of the Doctor returns to that moment in time and space, bringing along several incarnation of the Time Lord: John Hurt, David Tennant (the Tenth Doctor), Matt Smith (the Eleventh Doctor). 3 Doctors working together, 3 times greater nightmare to their enemies, including the Daleks. The current companion, Jenna Coleman (Clara) and Billie Piper (known as Rose Tyler or Bad Wolf) are also present. But Tom Baker too, the Forth Doctor, at the end of the episode.
I am not telling you the details of the great story written by Steven Moffat, it has too many turns (more or less unexpected) in the action. If I am starting to write the good or the best stuff that appeared in the episode I will only take you the pleasure and the surprise of watching the show. All I can tell you is that the Zygons, shape-shifting creatures that return in this episode of Doctor Who, provide an important item that help saving the planet Gallifrey and its natives from destruction. So that the Doctor will be able to return home some time in the future.
