Classic Who neophyte Allison lobs every question she can think of at our resident expert on all things 1963 to 1989. How has the TARDIS changed over the years, both inside and out? What about the theme song and the logo, especially after the recent debut of the 13th Doctor's? Which are the best companions, and which are the least effective? Do you need to be a completist? What are 10 (though Alasdair totally cheats and picks 11) essential stories? All that and more as we dive into some weird corners of Classic Who lore!
