Watching all of "Doctor Who" is a massive undertaking due to the show's extensive history, and the number of episodes and specials it includes. To help guide you through this time-traveling adventure, here's how you can proceed: ### Classic Series (1963-1989) The Classic series of "Doctor Who" consists of 26 seasons. The best way to watch them is in release order, starting with the First Doctor (William Hartnell) and progressing through to the Seventh Doctor (Sylvester McCoy). Note that many episodes from the First and Second Doctors' eras are missing due to the BBC's archival policies at the time. However, some of these have been reconstructed with audio and still images or through animation. ### TV Movie (1996) After the Classic series, you should watch the "Doctor Who" TV movie released in 1996, which features the Eighth Doctor, played by Paul McGann. This movie is considered a bridge between the Classic and Modern series, despite having a different style. ### Modern Series (2005-present) Starting with the Ninth Doctor (Christopher Eccleston), the Modern series picked up in 2005. You will want to watch these seasons in the order they were released. Pay attention to the Christmas specials and other special episodes, as they often play an important role in the story arcs. ### Specials and Mini-Episodes Throughout the Modern series, there are a variety of special episodes and mini-episodes. These should ideally be watched in conjunction with the series they pertain to, as they can provide additional context or fill in gaps. There are several online guides that can help you determine the exact order of these specials and mini-episodes relative to the main series episodes. ### Spin-Offs If you are interested in expanding the universe further, "Doctor Who" has several spin-offs, including "Torchwood," "The Sarah Jane Adventures," and "Class." While not necessary for understanding the main storyline of "Doctor Who," these series can provide additional background and entertainment. They can generally be watched in parallel with their corresponding seasons. ### Recommended Viewing Order for Modern Series (including specials): 1. Series 1-4 2. The Specials (2008-2010) which includes "The Next Doctor," "Planet of the Dead," "The Waters of Mars," and "The End of Time" Parts 1 and 2. 3. Series 5-7 including "A Christmas Carol", "The Doctor, the Widow and the Wardrobe" and "The Snowmen". 4. The Special "The Day of the Doctor" (50th Anniversary Special) 5. The Special "The Time of the Doctor" (2013 Christmas Special) 6. Series 8-10 7. The Special "Twice Upon a Time" (2017 Christmas Special) 8. Series 11-12 9. "Revolution of the Daleks" (2021 New Year’s Day Special) 10. Series 13 11. Future series and specials, which at the time of my knowledge cutoff include "Eve of the Daleks" (2022 New Year’s Day Special), along with any subsequent releases. ### Finishing Touches: - After you've caught up with the latest episodes, keep an eye out for new content as "Doctor Who" continues to be produced. - Take the time to explore classic episodes with missing segments through available reconstructions. - Consider delving into related media like audio plays, comics, and novels, some of which are officially recognized as part of the franchise's expansive lore. Finally, remember that viewing preferences can vary. While release order is generally recommended, some fans might suggest thematic or Doctor-centric ways to watch the show. However you choose to watch it, enjoy your journey through time and space with the Doctor!
