On one hand this episode has some rather fascinating things about it. I was really surprised, for instance, by how seriously the Britons took the pandemic (perhaps Jeremy's felt the need to affirm in his documentary that he'd locked-down properly, so that he wouldn't run afoul of the law - however I'm inclined to take the depiction at its face value, especially considering what the archive footage demonstrates the government having said to the public: "It doesn't matter who you are, [...] how old you are" - surely even with the limited data available then it would count as some pretty bold faced lying?..). The various tricks etc to do with sheep births and farming are also quite neat - however, truth be told about the former, there are a bit too many of these very naturalistic depictions scattered throughout. Otherwise, the cinematography is absolutely brilliant, as usual.
When it comes to things I've disliked (other than governmental lying) we have to count some stranger/less interesting scenes (with how much work there seems to exist on the farm, some of the nonsense they spend time doing is a bit grating), and, among other things, my usual hang-ups about unsophisticated language and imperial units of measurement.
