With documentary-makers these days, it can be hard to tell the difference between faux-naivety and the real thing. (Personally, I blame Louis Theroux.) Take BBC2’s Absolutely Fashion: Inside British Vogue (Thursday), directed and narrated by Richard Macer, who often seems suspiciously dazzled by whatever he sees: the editor’s office! The editor’s chair! He also has a tendency to proudly offer observations that aren’t necessarily as startling as he thinks: that the magazine appears to be largely run by women, for instance.
