Described as a visual and aural wonder is partly to the point. The aquatic sequences of whales are powerful, as are the sound captures of their song. But... for a documentary that is aimed to concentrate on this important subject it is at times irritating to say the least to listen to the scientists describing their work. American accents are fine, except when they are delivered in what seems to be the fashionable way of speaking, in a voice that sounds like laryngitis, especially when accompanied by totally unnecessary music that renders the words being spoken unintelligible. Poor whales... they deserve better than this!
