“She is crazy for going out there and doing it … but not bad crazy – good crazy!” That’s a friend of Sarah – the 38-year-old Brit who, after virtually dating Jgoy for two years without ever having seen him in person, is about to meet him for the first time in the Philippines. They are just one fascinating pair followed in this look at long-distance couples, narrated by Dawn French. The countdowns to their unions are undeniably thrilling. Hollie Richardson

Jerrod Carmichael Reality Show

The brutally honest US comic won an Emmy for a comedy special about coming out.

But how will his friends, parents and lovers feel about being filmed? Graeme Virtue
