Doctor Who's Steven Moffat reveals that he is still haunted by guilt over changing the Time War's outcome.
When Doctor Who returned in 2005 showrunner Russell T. Davies introduced fans to the Time War. This war spanned space as well as across time and was faught between the Time Lords and the Daleks for "all of creation". The result of this war was both races seemingly being destroyed and wiped out. The Time War quickly became a popular subject with fans because it defined who the new Doctor was. (The then 9th Doctor played by Christopher Eccleston and then 10th Doctor David Tennant. Even Matt Smith's 11th Doctor was influenced by the Time War.)
However, during the show's 50th Anniversary special "The Day of the Doctor" showrunner Steven Moffat reversed the outcome of the Time War and thus upset many fans who were very big fans of the Time War and what it brought to the story of the show. While being interviewed for Doctor Who Magazine #487, Moffat revealed his guilt about making the decision to do change the Time War.
""The Day of the Doctor was a success. Record ratings, awards, rave reviews. By any measure, it did alright. But two years later, I’m still haunted by the guilt.
"I know some of you, including friends of mine, were upset that we reversed the outcome of the Time War. My defence, however feeble, is that given the chance, the Doctor would do exactly that. And it was his birthday, how could I deny him that chance? What could define him more? This man who always finds another way? And there he is, at every moment of his life, proving to himself – literally – that there is always a better path.
"Ah, well. My heart was in the right place, at least. But in this job you always need two!""How did you feel when Moffet reversed the outcome of the Time War? What do you think about Moffat's excuse as to why he did it? Do you think it was the right move for the story of the show or did it take something away that needed to be there?
