Maybe...
That, anyway, seems to be the consensus across a pretty broad, and very large, public viewership. Certainly, I've never seen anything - in any media (not even for fiction, or classic movies) - to compare with Clarkson's Farm's 9/10 IMDB rating from 45,000 people - and indeed, Series 1 was running at something like 9.8/10 for a long time.
All this for a documentary!
There are some people who are allergic to Jeremy Clarkson, and cannot stand him at any price, and whatever he does - and have been working tirelessly for years to destroy him. But I regard him as one of the most original and supremely talented TV makers of the past several decades.
Clarkson's Farm is about his venture into farming, knowing essentially nothing about it - and Jeremy plays the part of himself, as usual - which (by all accounts) is simply an exaggerated version of real life; which is why it comes across as authentic.
The series is very funny; very interesting and surprisingly informative about farming; very revealing about the soul-destroying horrors of government and bureaucracy in modern Britain; and develops an unforgettable 'cast' of fascinating 'real'-life characters, of Dickensian colourfulness and variety.
The programmes are superbly crafted - as well as having great content; the editing and thematic shaping are stunningly well-done.
Of course - there have been much more profound and/or moving TV non-fiction series over the years. There is nothing like as much meat here as in The Ascent of Man, Time Team, Michael Wood's In Search of Shakespeare, or the BBC Historic Farms.
But at its level of immediately and generally accessible, informative light entertainment - plus a bit more - Clarkson's farm is as-good-as-it-gets.
Or better...
