Well, it's a tricky thing. I'm a huge fan of post-modernism in fiction, but there's no denying that it demands a lot of responsibility both of the creator and of the reader/viewer. There needs to be a critical eye on both sides for it to work.

the filmaking techniques that Eisenstein espoused as a reaction against capitalism have become the techniques used primarily in commercial advertising.

But of course. It's one of the central tricks of marketing: sell something mass-produced to people by convincing them that it makes them individuals, tell them to be rebels by following your narrative. (One of the scariest commercials I ever saw was for running shoes. It had a futuristic marathon race, where every runner was exactly alike, looked exactly alike, ran exactly alike, dressed exactly alike, all in grey in a black depressing rain... And then one of the runners suddenly started growing colours, and we saw that he was wearing THOSE running shoes, and he grew a face, and he grew his own clothes, and he smiled into the camera, every inch the superior being to the other faceless peons. ...AND THEN HE KEPT RUNNING IN THE SAME RACE. Ghaaaaa.) Hell, Eisenstein himself was selling the revolution.
