Two doctors refuse to regenerate, then get into some scraps, then regenerate after all. It's pretty great. * * * Shazam! We break from our normal programming to bring you our mildly belated review of the 2017 Doctor Who Christmas Special, Twice Upon A Time. Peter Capaldi's Twelfth Doctor, refusing to regenerate, goes to the South Pole for no particular reason. There, he encounters David Bradley's William Hartnell's First Doctor who, also refusing to regenerate, embarks with him on an adventure that Twelve really ought to remember, but doesn't. A not particularly eventful, but no less nostalgic or sentimental, journey ensues, as the two doctors are joined by the timeless glass memory receptacles of Bill and Nardole, as well as a moustachioed soldier with a conveniently coincidental lineage. In short, we really liked this one. * * * Check out WHOBACKWHEN.COM for more information, Doctor Who TV Serial and Audiobook reviews, ratings and ramblings, and loads more podcast episodes.
