My verdict? "Better than nowt", at least for part 1 of the 100 Best. Shame about the number of basic stupid errors - talking about the Honda 250 6-cyl, then showing lots of folk on 125 twins......"the first 50cc race" with great film of...a G50, a Manx;.... credit given in the high numbers to Robert Dunlop for the first 100mph lap, then later to Bill Ivy for the same feat. At times it became the Steve Hislop show, with several credits to him for basically the same achievements.
Errors on live telly are understandable - this many mistakes in a programme that could have had months to put together are a little less forgiveable!
