Clarkson's Farm was an excellent programme. As well as the reasons you mention, it highlighted some of the problems faced by farmers to a large audience, most of whom have never thought about farming before. Whilst undoubtedly there were some scripted moments of silliness (or perhaps more likely, discovering a problem then exaggerating it a bit, the "tractor train" when he got stuck at the bottom of a wet muddy slope springs to mind), it did seem a much more genuine programme that Top Gear or The Grand Tour.
