At some point he begins to have troubling dreams with a common theme of a coming, apocalyptic storm.
As the feelings from his night terrors bleed into the day, his behaviour becomes erratic and he obsesses with kitting out the storm shelter in their garden for the coming events.
Blimey. Michael Shannon and Jessica Chastain deliver what to me feels like the best portrayal of somebody having a mental health crisis I've seen in cinema.
It's amazingly understated. This is not the usual Hollywood take on it. Curtis knows things aren't right, tries to self diagnose, tries the low cost counselling options, tries sedatives and hides it from everybody until it can't be hidden any more. This is especially so because the subject is not an angsty teen, troubled artist, traumatised war veteran, or washed up celebrity. None of the boring go-to options for somebody in crisis.
He sits in the shelter at night, makes bad decisions and falls out with people, that's it but it feels so real.
Highly recommended 9/10.
