I was totally on board at first.

It was subtle. Nuanced. The performances were low key.. and subtle... and well... nuanced. Added to the normality of the town and the characters. Very peaceful despite the building dread. Then the dread didn't build any more. Nor did the excitement. As the movie went on, the more it felt flat. The subtlety and nuanced nature turned to dullness. Secondary characters died with no tragedy or sadness for them, nor humor. Like anything else in the movie, they just happen. In the end there is no payoff. Just a conversation between two characters that made me want to turn it off. I would not have missed anything if I had, aside from an end to Tilda Swinton's character, which did nothing more than create more questions. Cannot recommend.
