I'd seen a lot of unfavourable comments regarding this Once And Future story, but honestly I thought it was better than its reputation suggests. Although there are some pacing issues, and the story is rather basic, Jackie Tyler and Lady Christina make a heck of a fun pair. It's interesting hearing Jackie with a Doctor like the Sixth, who is so different from either the Ninth or Tenth Doctors. The Sixth Doctor is also unafraid of calling Harry Sullivan an imbecile like his predecessor!
