By all rights, All Creatures Great and Small should have been a boring TV series. A show about two country vets? In fact, Robert Hardy, who plays Siegfried Farnon in the show, thought it would bore the city folks and annoy those in the country.
But it works. For one thing, the acting is very good. But it is not just that, You get drawn in by the simple things of life — like dealing with Boris the cat.BTW, the show came out in 1978, when Hardy was 52. He is in his 90’s now and going strong! Enjoy!
