Your typical consumer of Who Do You Think You Are? on BBC One would almost certainly have been disappointed by last night's first instalment of the eighth series. There were no tears from June Brown, EastEnders' Dot Cotton, for a start. That is as it should be: what we got was a model of keen yet detached historical research, nothing from which Brown was going to take life-changing lessons, which is how facile this series can be.

Australia's cricketers used to call batsman Mark Waugh "Afghanistan", because (compared to his brother Steve) he was the Forgotten Waugh. It was a reference to the Soviet campaign against the Mujahideen during the 1980s. But few wars in recent-ish memory have been so deprived of the oxygen of damaging publicity as France's brutal struggle to hang on to colonial Algeria.

At the risk of sounding falsely pious, as this stunning film never is, Des hommes et des dieux, to give its differently emphasised French title, should be screened in every school and to every faith around the world. Xavier Beauvois sensitively takes us through the true-to-life decisions of seven Cistercian monks in the Algerian monastery of Tibhirine to stay and face not martyrdom but the life they have always known during the civil war between Islamic extremists and the government.

No, not “trance” in the sense of galloping four-to-the-floor electronic music made by people on Ecstasy for people on Ecstasy. This trance is the original ritualised half-conscious state produced by fast, intensely repetitive, rhythmic tribal music… OK, now I’m thinking about it, we are kind of on the same page here, you just have to appreciate that what this French/Italian/Algerian/Kabyle singer-songwriter is interested in is the spiritual origins of the braindead quantised noise favoured today by the average clubber.

Picasso the genius, the sensualist, the womaniser, the priapic beast. This much we think we know of the great Spanish artist. But how about Picasso the political activist? Picasso the supporter of women’s causes? Picasso the… feminist? Oh, yes, that Picasso. In a landmark Liverpool exhibition focusing on the years 1944 to his death in 1973, and bringing together 150 works from around the globe, Picasso becomes all of these things.
