Fascinating concept and a great series. Well, it would be if they had not cast uber-irritant Greg Wallace as the main presenter. His gurning, mockney barrow-boy schtick wears thin after 30 seconds. The other presenters add some gravitas and insight into the history of each product but I have to watch it with the subtitles on and a mute button handy to cut out GW's faked amazement as he patronises each machine operator who is unfortunate enough to be compelled to suffer GW's egotistical contrived patter.
