In the usual sense, this book is not "good".
But I gave it four stars! Why?
It's simple. Doctor Who is at it's best when it makes you think. About morality, politics, religion, or cosmology. When Doctor Who seeks only to entertain, it fails miserably (Yes, I'm looking at you, "Tooth and Claw"), or falls into utter banality, (Hello, "Time and the Rani").
So what about this book? Some of thse stories excel, The Diplomat's Story, The Tramp's Story, The Inquisitor's Story, and the Republican's Story among them, are wonderful examples of great Doctor Who, and really explore the central theme of consequences.
A few, like The Time Lord's Story are straight adventure yarns, and totally miss the mark on the central theme.
Some, like The Juror's Story take an interesting concept... and totally botch it. The Juror's Story will ONLY make sense to someone who's very familiar with every Doctor's era.
One, The Seismologist's Story, just doesn't make a whole lot of sense at all.
And one, The Schoolboy's Story, is the finest example of the theme of this collection. It explores the Doctor's character as, "I know this decision will not be good for those involved, but the Web of Time requires me to do it. What do I do?"
THe problem is, I don't care for the answer the book concludes on. SPOILERS WILL FOLLOW
Ultimately, the book concludes the Doctor is practically a "slave" to the Web of Time. Hold on... does anyone remember "Father's Day"? Nine found a way to change the history of his companion without consequence until Rose touched Rose. Contrast that to this book's theme that the "Web of Time" is absolute, and it is found wanting. The worst offender, despite it being a very good story, is "The Diplomat's Story." It's obvious Kathryn Sullivan can write, too bad she wrote for some other character calling himself "The Doctor" in that story.
All in all, a good collection of stories. A couple stinkers, but that's to be expected. Bt most are entertaining and thought-prevoking at the same time, and that's how I like my Doctor Who.
