I mean not to get all postmodern on you but I would argue most media stands alone to be interpreted. You can enhance or color a work by knowing factual and historical details but humans are pretty good at finding meaning in almost anything. Sometimes I think the less an object has on the surface the more we take it as a challenge to inscribe the thing with meaning.

On balance I think that's creativity in a nutshell and a good thing, though it can be taken to socially obnoxious lengths. The best kinds of "misreading" are where new and interesting ideas are born rather than just your run of the mill internet contrarianism. But the former type of creativity usually requires a kind of foresight and conviction we save for our revered term "artist."
