I think one of the issues is that there is a percentage of supporters who aren't really bothered about the quality of the action as long as their team wins. Ive been to loads of meetings over 35 years where I've been bored by the complete lack of any entertainment, yet others around me are raving about what they've seen.
Also, there seems to be a perception that close meetings automatically mean it's an exciting match, but that isn't always the case. One of the most exciting matches I've seen was Wolves beating Poole about 64 - 26 in our double winning season, yet the action was brilliant because Poole were jumping out of the start and our riders were rounding them up.
