Monster-mash together a Christopher Guest-style mockumentary on vampires and the comedic sensibilities of the Flight of the Concords crew and you get something like What We Do in the Shadows. Starring, written, and directed by Jermaine Clement and Taika Waititi, this film is capable of transitioning from deadpan hilarity to a genuinely creepy found-footage horror – and then back to ridiculous slapstick. So many films fail to establish a single tone, and somehow What We Do in the Shadows manages to nail them all.
