Great movie! Very realistic! I especially love how we get the perspectives of real people that act on their normal impulses/prejudices; they don’t know what’s going on and slowly come together as hope falls and realize something’s really wrong. Marsh does a great job as he ‘toe the line’ between wanting to tell what he knows and protecting the others’ (even at time his own) sense that they will be ok. It leaves a lot of questions, but seems it’s supposed to. It’s the character’s perspective of really not knowing what’s going on. I thought that was a great move.
