This basically has two essays for each of the first eight Doctors, and one each for Nine and Ten. The latter two, on Rose and School Reunion, are among the best in the book (though the rhetorical impact of the Rose piece is stronger if you know Sandifer's style); the other pieces which were new to me and caught my attention specially were the ones on The Movie and Mary Whitehouse.
The full list of essays here (and I won't link to them all) is The Web Planet, The Tenth Planet, The Enemy of the World, The Mind Robber, The Claws of Axos, The Rise and Fall of Ziggy Stardust and the Spiders from Mars, The Brain of Morbius, Mary Whitehouse, City of Death, Earthshock, Terminus, Attack of the Cybermen, Doctor in Distress, Paradise Towers, The Curse of Fenric, White Darkness, The Movie, The Adventuress of Henrietta Street, Rose and School Reunion. Worth noting that this includes three Cybermen stories, no Dalek stories, two novels, two pieces on music and an excellent attack on conservatism. I don't know if this will be available again in future but I'm glad to have snagged it while it was going.
