While the series itself is well done, with excellent filming and occasionally some new facts revealed, the biggest drawback for me is the choice of narrator. My husband and I both find Steve's voice completely wrong as a wildlife narrator, at least for adults. We've tried to figure out whether it's because he over-emphasizes virtually every word, or because his voice has quite a high pitch compared to other narrators, or whether his delivery is more suited to Blue Peter presenters. Whatever it is, I find myself switching off after the first minute and have to apply extra concentration to absorb any of the interesting information while trying to filter out its delivery. Generally I fail. Which is a shame, because as I said the series itself is essentially well done.
