Changes

You may well remember when the sticking of a number '2' after a film title was suggesting something of prestige - that the first film had been so good it was fully justified to have something more. That has hardly been proven correct, but it has until recently almost been confined to cinema - you barely got a TV series worthy of a numbered sequel, and never in the world of non-fiction. If someone has made a nature series about, say, Alaska (and boy aren't there are a lot of those these days) and wants to make another, why she just makes another - nothing would justify the numeral. But some nature programmes do have the prestige, the energy and the heft to demand follow ups. And after five years in the making, the BBC's Blue Planet series has delivered a second helping.
