I agree.
I'd also add that cultural critiques (usually) strike me as WAY over-generalized -- and that's because generalizations are necessary to make broad assertions about culture at large. From where I'm sitting, the most interesting aspects of cultural expression are (almost) always expressions of the particular and personal -- not the general.
From this perspective, discovering and building some sort of relationship with cultural expressions (visual arts, movies, music, books, whatever) is an individual's responsibility. And that is an existential thing. It's not served up on a platter. You've got to make it yourself. Like rostasi says, we're the "architects" -- and we're free to choose the materials that create meaning and value for ourselves -- because the former cultural abiters/authority figures have withered away.
Of course, it's not all roses. The "problem" with existential thinking is that freedom -- and lack of consensus -- is frightening to some (most?) people.
