I am no expert on Stonehenge (or any other prehitoric site for that matter) but I thought the programme was ok. I thought part 2 was better than part 1 and I liked the CGI showing how the site may have looked when newly built. I am sure this programme would have appealed to the majority of the viewers and perhaps given some of them a greater appreciation of ancient sites in general which muct be a good thing. It was certainly better than most of the rubbish which passes for 'entertainment' on TV.
