For that matter, "World War Three" (the second part of "Aliens of London") wasn't exactly a great title either ... personally I think the multi-parters should just stick with a single title, such as "The Empty Child, Part One" and "The Empty Child, Part Two." Partially because it feels more like classic Doctor Who, but also because the second parts tend to have weak names, it seems.
Only three more Eccleston episodes to go now. I would have liked for him to stay around a bit longer, or possibly have been Paul McGann the whole time, but he was an all right doctor. I don't think he'll ever rate as high as Baker or Pertwee, but they were a hella hard act to follow, weren't they?
