Before the opening titles of the new Doctor Who spinoff series, Class, a high school student has already been killed. Immediately after the titles, two fellow students remark that “everyone knows” how often teenagers at Coal Hill Academy go missing but “they just pretend” not to notice. For fans of Buffy the Vampire Slayer, this will only be the first wolf whistle indicating that the two series have much in common. There are so many similarities, in fact, that in a later scene, a character comes right out and says that Coal Hill, which is a “beacon” for interdimensional baddies, is like the “Hellmouth.” Ultimately, the new show (or at least its pilot) mostly lives up to the challenge of such lofty comparisons. And it’s a whole lot bloodier than Buffy ever was, too.
