A fun collection of Doctor Who trivia. A useful reference for fans, although calling trivia useful may be a contradiction in terms.
I would give it 5 stars but it's multiple references to the 1993 charity special Dimensions in Time drove me to look the special up on YouTube. Dimensions in Time is so bad it makes the Star Wars Christmas Special look like quality science fiction entertainment. Treating DiT as anything other than a weird footnote in the history of the Whoniverse belittles the entire business, which is not very big to begin with.
