A good idea with room for real conversation
Sharing a home creates situations in which different beliefs do more than collide abstractly. Everyday life sits alongside discussions of sex, death and the questions people bring to their faith. That mixture makes the premise interesting.
The conversations are strongest when participants do not merely recite their certainties. Personal doubts and prejudices then become visible. Different positions do not have to be artificially divided into a winner and a loser.
The people sometimes need more space
As convincing as the conversational premise is, I would have liked to follow some personal developments more closely. The series shows interesting reactions but occasionally moves on before their inner consequences become tangible. A compelling topic cannot automatically provide depth for an individual.
Private conversations with the camera add closeness. The quiet images help as well: Berlin and the flat do not become a frantic reality-show arena. That suits a programme whose appeal lies in listening and accepting differences.
Verdict
The first season of Against All Gods has a strong central idea and enough genuine friction to create interesting encounters. The open conversations in particular make it worthwhile.
An even stronger result would give more time to changes within its participants. Even as it stands, this is a respectful documentary about people with different convictions learning to share everyday life.
