AS that doyen of documentary makers Molly Dineen knows, sometimes it is the things left unsaid that are the most worth talking about. After ten years away, the award-winning director was back on the small screen this week with Being Blacker (BBC2, Tuesday, 9pm). The obvious first question was, “Good golly Ms Molly, where have you been?”

When she introduced her subject, Brixton reggae shop owner Blacker Dread, and revealed that she had only intended to film his mother’s funeral but stayed around for a further three years, I wanted to know how she supported herself for all that time. Maybe I’m just too nosey.

Dineen certainly had a rich subject in Blacker, who she first featured in a student documentary when they were both 19. Now 55, the man who had arrived in Britain from Jamaica as a child was at a critical point in his life and in his relationship with the country he had never wanted to come to in the first place. Like so many others of that generation, his parents thought a better life, and a warm welcome, were waiting. In some cases it was, but not for all.

Dineen has a gift for disappearing into the background. While she is friendly, she is not her subjects’ friend, as when she asked Blacker’s ex-bank robber pal whether it didn’t make made him feel “a bit of a s***” scaring someone. Being Blacker had its share of revelations and electrifying moments, but at an hour and a half it also had its slow stretches, most of them when he left the screen.

What Would Your Kid Do? (ITV, Tuesday, 8pm) ended its run just as it was getting into its stride. A cross between Mr and Mrs and The Secret Life of Four-Year-olds, the ITV show set out, in the words of host Jason Manford, to “ask more questions of your kids than a Jeremy Kyle DNA test”. Stay classy, ITV.

Watching six-year-olds being tested on their ability to tell the truth and solve problems was a giggle, with science bits shoehorned in just to show there was a serious purpose to the carry on. Did you know, for example, that telling white lies is a sophisticated cognitive process crucial to development? Judging by the way Manford read out the card it was news to him, too.

Featuring three sets of relatives having to predict what their youngsters would do in a situation, the programme struck gold in a family from Glasgow. Young Blake had more energy than a battery factory, the gift of the gab, and a sweet streak a mile wide. Alas, he was a constant revelation to his mum and dad, who came last. “I’m surprised we got any points,” said mum as dad planted the biggest smacker on Blake’s head. There were no losers in that family.

Next week, Scottish Conservatives leader Ruth Davidson is on The Great Celebrity Bake Off for Stand Up to Cancer (Channel 4, Tuesday, 8pm), so I dropped in to check out the competition. Let it never be said this column is useless.

The celebs being put to the bake test this week were a lad from the dance group Diversity, the bloke who used to be on The Apprentice and now does Countdown, some musician, and a Loose Woman. Unlike this column, Countdown’s Nick Hewer was useless. Now I’m no expert of the calibre of Paul “Fat Paul Newman” Hollywood, but when someone says their cake looks as though a dog with tummy trouble has been in the famous tent it does not bode well. “I don’t know where it went so terribly wrong,” said Lord Sugar’s old mucker. “I’d say series four of The Apprentice,” Noel Fielding shot back.

Here’s a starter for ten. Is it possible to put Room 101 into Room 101? I only ask because Room 101 (BBC1, Friday, 8.30pm) has now been on TV for 24 years and some weeks you do wonder if it has simply run out of things for celebrities to say they hate. This week, with Bill Bailey having a go at taramasalata and Una Stubbs up in arms about people talking loudly on their mobiles, the distinct sound of a barrel being scraped could be heard. What keeps the show on the road is the host, Frank Skinner, who gives every impression of knowing the show would be called Pointless if that title had not been already taken, but keeps firing decent gags anyway.

Homeland (Channel 4, Sunday, 9pm) is getting to that familiar point where it is on the brink of triumph or disaster. The president’s chief of staff looks like a wrong ‘un; a shock jock has engineered a Waco-style stand-off with the FBI; the last black hair in poor Saul’s beard has gone grey; and Carrie, wouldn’t you know it, is off her meds. “It’s Crazytown,” declares the former CIA agent. As long as Nick Hewer doesn’t open a cake shop there, I’m in.
