I'm questioning the validity of using the general population as an authoritative source of film critique. Although it's probably silly to ask for an artistic critique of an action film at all.

Far from it; action films are extremely interesting from an artistic POV because they are often so uncontrived that they offer an unusually direct insight into the society that made them. John McTiernan's Predator is a superb film, for example - it's 30 years old and still plays well on TV or the big screen.
Who said I was using the general population as an authoritative source of film critique?
"regarded by many as the greatest "action" movie of all time" means just what it says. I never claimed nor even implied that the view was authoritative simply because it was widely held.
I think that's a reasonably defensible statement - http://www.metacritic.com/movie/the-dark-knight.
