It's called Napolislam - and it's essentially the story of ten Neopolitans who have converted to Islam.
It's a well made film that seeks to show how integration has worked to some extent in Naples in ways that it hasn't worked in other parts of Europe.
Like any good documentary it has subjects who are riveting and others who are not, but it was a stroke of genius on Pagano's part setting the documentary in Naples.
The devastating images of Naples (a place that I just looooove nonetheless) really reinforce the sense of alienation and contempt that a lot of the subjects have with the current Italian state.
Worth checking out. If you're not good with Napoletan
