Doctor Who fans still can’t let go of the Tenth Doctor and Rose Tyler

Twenty years ago, David Tennant stepped into the TARDIS for his first full-length Doctor Who adventure, “The Christmas Invasion.” That episode did so well for the sci-fi family show that it kickstarted the well-loved British tradition of the Doctor Who Christmas special — and cemented a fan-favorite duo. The playful, feel-good chemistry of The Tenth Doctor and Rose Tyler (Tennant and Billie Piper) solidified their adventures across time and space as a monumental era in Doctor Who history. There have been so many different Doctor/Companion mash-ups throughout the years, but the Tenth Doctor and Rose remain an incredibly beloved pairing that fans are still discussing on the 20th anniversary of their Doctor Who era.
