Series 3 Episode 1: Smith and Jones

Summary:
Martha is on her way to work when a strange man appears in front of her and takes off his tie before disappearing again. She comes to the hospital and sees the man again when she is on the ward round with the chief physician but he doesn't recognise her. When she listens to his heartbeat, it sounds like he has two hearts. Shortly after that a strange storm starts around the hospital and the whole building is teleported onto the moon. The Judoon appear in their spaceships and it seems that they are searching for an alien being that is hiding in the hospital. Martha soon finds out that the strange man with the two hearts is an alien as well and tries to help him to save all the people in the hospital before they run out of oxygen. They are able to trick the alien to drink the Doctor's blood and so the Judoon are able to find the shape shifter. The hospital is sent back to earth and the Doctor vanishes. Will Martha see him again?

I think this episode is a great start to the third series of Doctor Who and a great introduction for Martha. She is so different than Rose but nonetheless a great companion for the Doctor although he doesn't appreciate that at the beginning. The special effect are amazing especially when you look out of the hospital and there is the surface of the moon. It really looks like the whole building was placed onto the moon. The Judoon are a strange alien race in their armour and with their rhino heads. "Smith and Jones" is a funny story with the alien who drinks blood through a straw. The episode has many funny moments and somehow you know that the Doctor will manage to save the people somehow. I like the way how the first minutes of the episode are connected to the last scene when the Doctor shows Martha that he really is a time traveller and he promises her a trip to thank her for her help. Well, we all know that she doesn't get only one trip.
