Technically, the series bears marks of desperation. Instead of footage which visualises the past and evokes its feel, we get dim, unconvincing dramatisations; slow shots over static, feebly researched pictures; predictable, anachronistic music; contrived views of the presenter in unnamed, unexploited locations. Schama fidgets as he delivers a script overburdened with words and narrative. He is one of our most brilliant wordsmiths, but television is above all a picture-show and you can never exploit its potential to the full if you start with words.
