While many episodes of Doctor Who start off with a creepy-yet-lighthearted cold open, 2007’s “Blink” (season 3 of the modern era of Doctor Who, episode 10) goes full horror-mode. It’s 1 a.m., and a lone young woman named Sally (Promising Young Woman star Carey Mulligan) is exploring a dilapidated, abandoned home. Venturing further inside, Sally pulls at some loose wallpaper, and is horrified to find her full name somehow scrawled across the wall beneath it.
