I wonder how the casual fans and laymen looked at this documentary. It probably was hardly interesting for them at all. And I don't think that they really learned anything new about The Beach Boys apart from maybe the fact that they actually did anything between "Good Vibrations" and "Kokomo"...
Agreed. Esp. with a period such as this, one must make a real effort to elucidate and explain. Diehards will enjoy that too.
