There are some people who say the urban fox is vermin.

A nuisance. A scavenger that has deserted the hedgerows and fields of the countryside to pick over the remnants of kebabs and pizzas in the city. There are even some people who say the urban fox is a danger to their children.

But there is another species that is much more annoying than foxes and that's the human beings who complain about them. This species also survives on kebabs and pizzas and has a very distinctive call: a kind of moany whinge that you can often hear on news reports and documentaries.

There was a prime example of this kind of human in the first episode of Foxes Live (Monday, Channel 4, 8pm), a natural history documentary tracking city foxes. The human's name was Natasha David and she displayed much of the stupidity the human species is renowned for.

Natasha started off by showing us a picture of a fox that used to come into her home. "I posted the picture on Facebook," she said, "and everyone loved it because it was so cute and cuddly." Then one night, she said, the fox came into the house through a window she'd left open and bit her on the foot. The following night, the window was left open again and Natasha was bitten again.

Natasha was pretty upset by this – and even more upset that the fox had made off with one of her Alexander McQueen shoes (the camera zoomed in for a close-up of the shoe that survived). "I was angry," said Natasha. "The council weren't going to do anything about it." Because the council should do something. About everything.

Fortunately, Tim Wass, the former chief officer of the RSPCA, was around to put the whole affair into context. What the fox was doing, he said, was natural behaviour; it was not attacking Natasha, this is just what happens when foxes become too associated with humanity and we should not let these so-called attacks guide our policy on foxes.

Not only was this the kind of common sense we need to hear on the subject of foxes, it was also a reminder that good nature documentaries can shed just as much light on humans as they do on animals. As the story of a vixen raising her three cubs under a garden shed unfolded, the fox emerged as a dignified, beautiful creature. Sadly the same could not be said of the human being complaining about the loss of a designer shoe.

The American remake of The Killing (Wednesday, Channel 4, 10pm) was back this week and the twist, like a knife, was that the picture that solved Rosie's murder in the last series could have been faked. In other words: her killer is still out there.

American remakes often don't work but this one does because it understands what made the original version so wonderful. First, it unpeels the sheen over ordinary families and peers at all the muck and dirt underneath; and secondly, in the character of Sarah Lund, it presents one of modern television's most convincing women. For 10 years or more, we got Sex And The City and Desperate Housewives, full of women made of tight skin wrapped in tight clothes. Now, at last, we could be entering the age of the realistic woman.
