The stylishness and eerie visual sophistication creates an often unsettling, almost surreal vibe that emphasizes how disconnected they all are from the rest of the world. And the very grin-and-bear-it style Brit stiff upper lip that they try to maintain (Eve and Jean even have time for a spot of tea in the kitchen as they try to figure out what’s going on) adds to the sense of surrealism. Overall, the movie doesn’t rewrite the book of shock (despite the jump scares), but what you get is a fast-paced scare flick with an ending that could have been creepier.
