Series 2 Episode 4: The Girl in the Fireplace

Summary:
It is Mickey's first trip in the Tardis, which brings him, the Doctor and Rose onto a spaceship in the future. There are no people on board but a fireplace that is a time portal. Through the fireplace the Doctor meets Reinette as a girl and discovers that she is haunted by clockwork robots who scan her brain. He meets her in different stages of her life and soon finds out that she is Madame de Pompadour. Rose and Mickey have a look at the spaceship and they find human body parts integrated into the ship. When the clockwork robots try to kill Reinette the Doctor tries everything to save her even if that means that he can't return to Rose and Mickey. Can he find a way back?

I really liked this episode especially because of the time jumps but in the end it's a really sad episode because the Doctor comes too late. The clockwork robots look amazing and it must have been so much work to build them but they are really brilliant and a bit scary. There is a lot of emotion in the episode, for example when Rose thinks she has lost the Doctor forever or when the Doctor reads Reinette's last letter. I love the scene with the horse on the spaceship and how the Doctor keeps it as a pet. That's really cool. You somehow feel the joy of Mickey who is on a spaceship for the first time. All in all, a beautiful episode with a bitter sweet touch.
