The list author says: "The purpose of this list is to assist new Doctor Who fans as a guide for buying the best Classic DVD episodes without sifting through the entire 160 programs over the course of the original 26 year run.
In addition to my own opinions, input from Amazon user reviews, Doctor Who fan sites and other various online user lists were all taken into consideration. Of course, there are as many lists as there are Doctor Who fans and so I needed to choose my criteria as objectively as possible. In the end, I decided on the following order of importance...
1) An engaging story plot - This is further defined as a story that is interesting, makes technical sense, has reasonable continuity and a satisfying resolution.
2) Dialog - This is more based on quality than style. For example, some fans do not like the humorous Tom Baker or the violent Colin Baker, neither of which is a factor in this list.
3) All Doctors are treated equally - Someone may just despise Sylvester McCoy and not select a representative number of his episodes, even though some are good.
4) All Companions are treated equally - Fans tend to play favorites but it is important to realize that many people like myself enjoy companions like Tegan and Adric for what they bring to the program, even though that may not be as strong as Ian and Barbara.
5) Continuity in regard to the history of the show. In that respect, shows that contain major events such as a regeneration, arrival/departure of a companion, or a critical piece of knowledge, are given a higher priority.
6) Special effects, costumes, and set design does not detract from an episode in most cases. However, there are a few exceptions like Warriors from the Deep where the design is so poor that it draws attention to itself and thus detracts from the story.
Please let me know if you have comments or suggestions...Thanks and enjoy!!!
*Note: Box sets containing multiple episodes bring the total from 40 to 50."
"A great stand-alone story and a perfect starting point for those who are new to Classic Doctor Who. The side characters Professor Litefoot and Jago are most endearing and my personal favorites in the classic series."
"These first two stories are interchangeable for the #1 spot. They are quite different with this story requiring some previous knowledge of the Daleks to fully appreciate. If you are new to Classic Doctor Who, I would begin with The Talons of Weng-Chiang above."
"A wonderful connected six story box set that includes: The Ribos Operation, The Pirate Planet (my favorite), The Stones of Blood, The Androids of Tara, The Power of the Kroll (forgetable), and The Armageddon Factor."
"Unfortunately, most of the second Doctor's episodes played by Patrick Troughton do not survive. However, this one and The Invasion are his best. Also notable as the longest single story in Doctor Who history at 10 x 25 minute episodes."
