The first series of the rebirth of Doctor Who in 2005 is something special for Doctor Who fans. It takes awhile to get used to Christopher Eccleston's portrayal especially if you've already seen the later series with David Tennant and Matt Smith. It also takes Billie Piper a few episodes to improve acting wise but all up it's a brilliant reintroduction to the world of The Doctor and the behind the scenes special features are very cool. It's a pity Eccleston fell out with the producers of the show and couldn't have been used more in the 2013 50th anniversary special.
