The Problem of Standing Aorund Too Long

Lately I've been noticing a trend in critical theories, and really any sort of theoretical socio-politi-cultural field. It basciacally runs down that after a field has been arund for a length of time it develops a robust body of literature and hypothesis. Eventually this body of knowledge and thought will actually become a hinderment to the development as a field because the academic process begins to mandate wading through an ocean so deep and wide that talented, smart, intuitive people begin to get lost in the depths, thier innovative ideas crushed under the pressure of making sure that they're not saying somethign that's already been said.Film is startinf to reach a similar threshold, where it's very hard to convince someone that you've got a new and unique idea because they want to stick it in one of the billion existing boxes that stuff has been filed in. This is kinda what's at the heart of the "you can't do that" school of literary criticism. If somone great didn't do it, it can't be done. In most fields, if Marx didn't say it, or if you havn't devoted your life to figuring out if Marx said it, you can't do it.
