Since 2005, when Doctor Who was relaunched, Series Four received the highest average episode rating with 8.35 out of 10 on IMDB.
The series, which aired on the BBC in 2008, starred David Tennant as the 10th Doctor alongside Catherine Tate as his main companion, Donna Noble. Both actors will reprise their roles for the three-part 60th anniversary special, ahead of Ncuti Gatwa’s series.
Series Five, which aired throughout 2010, has the second highest average episode rating of 8.08 out of 10. This was Matt Smith’s debut series as The Doctor, and starred companion Amy Pond, played by Karen Gillan, alongside appearances from River Song (Alex Kingston) and Rory Williams (Arthur Darvill). This series gave new fans an introduction to the franchise, without needing to catch up on the long history of previous Doctors.
Series Three shares third place for the highest average rating with 8.05 out of 10. Airing in 2007, David Tennant’s Doctor was joined by Martha Jones, a new companion played by Freema Agyeman. This series featured the return of prominent characters from earlier series, including Captain Jack Harkness (John Barrowman) and The Master (John Simm).
Series Nine also received 8.05 out of 10 and starred Peter Capaldi in his second outing as The Doctor. The series, which ran throughout 2015, featured companion Clara Oswald, played by Jenna Coleman. Series 9 ended with Coleman’s departure from the show after three series, with the Doctor losing his memories of her in the finale episode.
Series One has the fourth highest average rating with 7.91 out of 10. Airing in March 2005, this was the return of the Doctor Who franchise after a 16-year long hiatus. Audiences were introduced to Christopher Eccleston as the ninth consecutive Doctor alongside companion Rose Tyler, played by Billie Piper. While Eccleston only played the Time Lord for one series, Piper continued the role into the next series alongside David Tennant.
Over 800 episodes of Doctor Who will be coming to BBC iPlayer on November 1st ahead of the new series, along with an eventual presence on Disney+ for viewers outside of the UK.
