Re: Doctor Who Just Replaced Captain Jack Harkness In The Most Perfect Way

 So, Jack and Rose have now essentially been recast by Russell T Davies, while
leaving the original personas intact. The showrunner clearly has a certain
group of archetypes for whom he enjoys writing, so there could be more
replacements coming in the future to accommodate Davies' preferences. Of
course, the Doctor has also been replaced, but that's a writing mechanic
that's at the very heart of the show. Barrowman and Piper's younger
counterparts now stand the chance of being as influential as their Doctor Who
predecessors.
