Did we like it?

Keith Allen may have his faults (history of boorish behaviour, daughter Lily, Vindaloo) but his appearances in Robin Hood and Bodies were memorable and his Channel 4 documentaries (about Lauren Harries and Michael Carroll) have been gems – and this was no exception.

What was good about it?

• Allen’s easy-going, never-awkward attitude to a bunch of youngsters from Tourettes Scotland, led by John Davidson of 1989 documentary John’s Not Mad fame. Allen dealt with them well as a collective, but was at his best in the one-to-one interviews.

• The revoicing of Cliff Richard’s Summer Holiday with expletives added

• The flashing of every spat-out word on to the screen was a good stylistic device.

What was bad about it?

• The road trip element was a little overplayed, with constant references to the frailty of the London Transport Routemaster bus driven by a black Christian from Ghana who took the involuntary cries of “Nigger” in his stride (although he did moan a bit too much about his numb toes)
