I think you should start with Series 1 . Christopher Eccleston is absolutely amazing . Every regeneration of the Doctor gives us something different . Eccleston ' s 9 is fresh off the time war and is raw and angry and hurting . He ' s learning to function and trust again . It ' s a beautiful thing to watch and the connection to Rose is an important part of that story . To me , it ' s good to see it from the beginning . The show has more of an impact overall , I think , if watched in order . You certainly don ' t have to , but , things will make more sense and you ' ll make more mental and emotional connections to different characters and circumstances if watched in order . Also , one of my favorite episodes ever , The Doctor Dances , is in series 1 .
