How has the portrayal of the Doctor evolved over the years?

Doctor Who is a British television series that has been on air since 1963. Over the decades, the show has gone through multiple changes, but one of the most notable is the evolution of the Doctor's portrayal.

When the show premiered, the Doctor was played by William Hartnell and was portrayed as a grumpy, old man. As the show went on, the Doctor became more of a hero figure and his demeanor became more lighthearted.

In 1974, the Fourth Doctor, played by Tom Baker, was introduced and he became the longest-running Doctor to date. His portrayal was quirky and somewhat eccentric, which set the standard for future portrayals.

The revival of the show in 2005 saw Christopher Eccleston take on the role of the Ninth Doctor. His portrayal was more serious and angsty, which reflected the darker tone of the show at that time.

David Tennant and Matt Smith followed as the Tenth and Eleventh Doctors respectively. Both of these portrayals were more comedic and light-hearted, which helped to bring a new generation of fans to the show.

Peter Capaldi took on the role of the Twelfth Doctor and brought a gruffer, more no-nonsense portrayal to the table. Finally, Jodie Whittaker became the first female Doctor in 2017 and her portrayal has been one of determination and bravery.

The portrayal of the Doctor has evolved greatly over the years, but one thing has remained consistent: the Doctor is always a hero who fights for the greater good.
