Has anyone seen the movie, "100 Mornings" ?
Its set in Ireland, in the mountains of County Wicklow. Apparently 2 months after some kind of collapse event. The grid is down, communications are gone, the local Police sergent has become the king of the village. It seems to have been very well researched and goes into the emotional and physical issues of isolation, hunger, relationships with family / neighbours.
I think it's well worth watching, it's obviously set in rural Ireland, which has a particular set of circumstances and environment.
