Tom Baker, the most popular Doctor internationally, had a succession of wild and colorful adventures that are more entertaining and a lot funnier than most of the sitcoms on TV today. The early episodes, starring William Hartnell, were mysterious and realistic in tone, and are terribly underrated by the show's fans. Television remains the ultimate format for Doctor Who, however, and the series has something to offer for just about everyone. Although the concept is beginning to seem a bit old now, great 'Who' stories are still coming out all the time. Since the show's cancellation, Doctor Who has been sustained by hundreds of books and radio shows. This format gave the show an amazing freshness and allowed it to last for over a quarter of a century without becoming stale. Even the Doctor himself was periodically replaced by a new actor, 'regenerating' his body whenever he was on the verge of death.
Every few weeks, the Doctor would travel to a different planet or time, allowing the show's cast, setting, and tone to constantly change. The show chronicles the adventures of a time-and-space traveling alien who wanders the universe battling evil conquerors, ruthless corporations, and other exploiters of the innocent and oppressed.
Doctor Who ran for 26 years, and its last episode was as fresh and imaginative as its first.
