I don't write reviews about movies, but some of the negative reviews are just off. We go to a couple of movies a year. This held our attention from the start. The cast, characters and film technique were perfect. Was it a horror movie, not really. However it had you questioning what was happening and who to believe throughout. It didn't need more apocalyptic scenes or blood. That was left to the viewer, again perfect. My husband and I discussed this the whole way home, which means it was a really good. If there was a subtle twist or something to make you question further at the end, it would have been even better.
