It took the original run of Doctor Who eighteen seasons to reach its Fifth Doctor. The new series has reached that milestone in ten seasons, as the BBC has announced that Peter Capaldi, the Twelfth Doctor (fourth of the current run) will be leaving the series at the end of Series Ten, due to start April 15th of this year:

The decision seems to be on the part of Peter Capaldi rather than the BBC, which I imagine would have liked to have a familiar face on screen as new showrunner Chris Chibnall takes over for Series Eleven. Not that I can blame Capaldi, since the series has seemed an afterthought on the part of the BBC for some time, with extended hiatuses the norm.
I must confess that I never quite warmed to this iteration of the Doctor. Though I greatly appreciated the return to the more mature and irascible sort of Gallifreyan as depicted by William Hartnell and Patrick Troughton, Capaldi’s Doctor never seemed to have scripts with sufficient depth of character to allow him to really shine. His portrayal might have fared better in the original run; I can see him performing quite well in some of Troughton’s stories, and Capaldi has always appeared to have a love of the show and the character that matches Hartnell’s similar appreciation for the role.
The timing of the announcement seems a bit odd, as an entire series of Capaldi’s era, plus a Christmas special, remains to be aired. Ostensibly, there’s no way to keep this news silent once the decision is made, but I wonder if the inevitable speculation frenzy over the next Doctor will overshadow the stories to come. And will the BBC choose (and announce) a new Doctor a good year before we can expect a Series Eleven? Only time (which Time Lords seem to have in spades) will tell…
