More Doctor Who geekiness, this time focussing on the tenure of the Second Doctor, Patrick Troughton. What's really amazing about these books is not just the depth of their intelligence, but the breadth. In addition to the enjoyable fan-wankery typical of such guides - obsessive continuity, objective critiques, behind-the-scenes lore, etc. - nearly every story has an accompanying essay, sometimes only tangentially related. A selection of titles include "Did Sergeant Pepper Know the Doctor?", "How Buddhist is this Series?", "Does Plot Matter?" "Did Doctor Who End in 1969?" and "Cultural Primer: Why the Radio Times?" Look, sounding smart about one thing is easy, and sounding smart about a TV show isn't much of a stretch. But it's typical for these essays to reference or touch on such a vast array of seemingly unrelated subjects while answering their proposed question; the essay "What Planet Was David Whitaker On?" references the four elements and the quintessence, Roman gods and their metallic & planetary counterparts, cinnabar & the secret of immortality, the four humours, "the mercury tumbler-switches of wartime bombs" ... And that's just various elements of one essay among many. (The essays that focus more on the sociological and cultural developments of the 1960s are even more fascinating.) Eric & William have been borrowing these books after I finish them and likewise enjoying them immensely - and, since they (unlike me) have not been watching all the episodes that the guide talks about, that's pretty noteworthy.
