Isolating one gas station photo is seriously doing an injustice: does every single creation need to fully justify the reputation of the creator? Does every single creation of the artist need to be equally and fully explicable to every viewer? That's a terrible burden to ask of all art.
Further, context is incredibly meaningful, and separating one element from a large body of work is not just putting it at a disadvantage, it is deliberately misrepresenting it. Bernd and Hilla Becher are photographers I've loved for years, and it would be amazingly easy to pull one photo out of, say, Framework Houses, and say it's trite and boring. But when you look at the whole series, you find that the concept is much deeper and more interesting than any single element in isolation would suggest. The work is an aggregate, and needs to be looked at as such.
What the reputation of an artist should do, when you encounter something that seems initially inconsequential, is cause you to look more carefully, to see if you can discover why someone who has produced so much other consequential work saw something consequential in this. It would be nice to say that all work should be so looked at, but we just don't have that kind of time.
