This past weekend, the BBC aired Terry Pratchett: Back in Black, a part-drama, part-documentary tribute to mark the death of one of fantasy's most beloved authors. Typically, these sorts of specials about dead celebrities include "talking head" insight from fellow celebrities, but rarely cover the indelible mark left on seas of ordinary fans. Back in Black does, and it's what makes it stand out as a stunning farewell to Pratchett.
