After 
                      adventuring through time a lot longer than he originally 
                      planned, the Doctor returns Martha home but just as she 
                      is about to have to get used to having a normal life again, 
                      the TARDIS returns. As he was saying goodbye to Martha he 
                      overheard prominent scientist Professor Lazarus announce 
                      on the news that he was going to change the human race forever. 
                      Intrigued by what he had planned, the Doctor decides to 
                      investigate and he needs Martha’s help to get him 
                      into the experiment presentation.  
                    
After 
                      battling his greatest enemy in the past, the Doctor returns 
                      to modern day Earth to take Martha home, but he can’t 
                      stay out of trouble for too long. 
                    As we 
                      hit the half-way point of the new season, Doctor 
                      Who is still hitting the ground running and this 
                      is the first episode to start introducing plot points that 
                      will build to the dramatic finale. Professor Lazarus’s 
                      experiment will change the evolution of human kind forever 
                      and the Doctor is intrigued because he knows absolutely 
                      nothing about it. 
                    The 
                      Professor enters his hypersonic sound wave machine an old 
                      man but when he exits, after being saved by the Doctor, 
                      he is transformed into a younger version of himself, in 
                      essence regenerating. Knowing that should be impossible 
                      for human science, the Doctor realises that everything might 
                      not be as it seems and the Professor might have awaked dormant 
                      genes that could have catastrophic results for him and the 
                      rest of the guests at the experiment demonstration. 
                    Now 
                      six episodes in, it is clear that Russell T. Davies and 
                      his creative team have been given a much larger budget for 
                      this season. The creature that Professor Lazarus becomes 
                      is completely computer generated and looks extremely good 
                      for British television.
                    While 
                      it might not be up to the standards of the much larger funded 
                      American counterparts, it is the creativity and design of 
                      the creature that has to be applauded. It is in the storytelling 
                      where this show excels however, successfully mixing all 
                      out action with an underlying story that sets up things 
                      to come. 
                    The 
                      episode also lets us get to know more about Martha’s 
                      family. Her overbearing mother, played by the excellent 
                      Adjoa Andoh, wants to know what she has been doing and who 
                      the Doctor actually is. Her sister Tish, played by Gugu 
                      Mbatha-Raw, gets drawn into the action after being jealous 
                      of all the attention that Martha gets. Her brother Leo, 
                      played by Reggie Yates, doesn’t really get enough 
                      screen time to develop however. They are very different 
                      from Rose’s friends and family, overprotective and 
                      competitive, making you understand why Martha is drawn to 
                      the Doctor. 
                    The 
                      League of Gentlemen’s Mark Gatiss has real fun 
                      as Professor Lazarus, showing that he can handle dramatic 
                      as well as comedic roles with ease. There is also a cameo 
                      by Coronation Street legend Thelma Barlow as Lady 
                      Thaw, the woman who thinks she has a future with the now 
                      young professor. 
                    ‘The 
                      Lazarus Experiment’ is an action packed episode that 
                      is made all the more intriguing by the introduction of the 
                      mysterious ‘Mr. Saxon’ character, someone who 
                      will play a major role in the rest of the season. Doctor 
                      Who fans have never had it so good.
