There's more to this DVD than one might think, in that it features an enjoyable and interesting commentary on the areas covered. As expected, the aerial views are absorbing, and backed up with ground-level shots, old maps and pictures. Sometimes you'll want to reach for the pause button, as some of the views are soon over and you haven't had to time to take everything in. However, with the film running at an impressive 97 minutes (though you can watch each chapter on its own), you can see why they had to edit the filming carefully. The fascination of the views from above is such that some areas, such as the City, Docklands or the West End, warrant a full film all of their own. As a synpopsis of many key areas though (including sites of infrastructure and railways), this is an excellent DVD.
