To celebrate the 50th Anniversary of Doctor Who, BBC Home Entertainment is releasing the best serial from each of the eleven Doctors. The first release features the first four Doctors, William Hartnell, Patrick Troughton, Jon Pertwee, and Tom Baker, from the years 1963-1981, each in one classic episode, The Aztecs, Tomb of the Cybermen, The Spearhead From Space, and Pyramids of Mars.
My introduction into the world of Doctor Who was when the episode "Rose" aired on the Sci Fi Channel (now known as SyFy) in the spring of 2006. I was aware of the previous series that aired from 1963-1989, but I had never watched an episode before, though I had watched the Peter Cushing's version, Doctor Who and the Daleks and Daleks - Invasion Earth: 2150 A.D., so I was eager to watch the four-disc set, which I received free of charge from BBC Entertainment in exchange for my honest review.
Each episode can be watched in its original four-part version or as a feature presentation with an introduction by Steven Moffat. For a bonus, there is a profile special on each doctor.
