Even if it turns out to be a five-minute bit of pointless fluff sandwiched between BBC newsreaders singing something like Queen's
Bohemian Rhapsody and Terry Wogan, I'm glad Peter Davison's back.
Besides, regardless of what everyone here thinks - positive or negative - I'm willing to bet we all watch it anyway and that it'll be on the Series Four box set at the end of next year.

Not to mention that this'll probably be the only time in the new series we'll ever see the Doctor meeting one of his past incarnations.
Anyway, with Steven Moffat writing, it can't possibly be any worse than
Dimensions in Time...
