I just came back from viewing "Eternal Sunshine of the Spotless Mind," and I freely admit that it has tired me out. If there has ever been a movie fashioned in such a post-modern way, this is it. I suppose that it's somewhat reminiscent of Memento in that way, you have to piece the puzzle together as you watch it in order to obtain any story line.
However, and you are more than welcome to correct me if I'm wrong, I admitted long long ago that Philosophy is not my area of specialization, I'm not sure if the actual theme of the movie is really post-modern at all. From what I remember of Contemporary Fiction, the idea is that we write our own history- there is no overarching history, each person has the control and the right to form their own story. Eternal Sunshine dangles the option of changing the world, changing your story and re-writing it in the true post-modern fashion. And then what do they do? They snatch it back up and say "Fate is fate, buddy. You can't escape it. Destiny. Predestination. Call it what you will. You can run but you can't hide!" Ok, so I'm paraphrasing here. I really hate outright spoiling movies for people, so I am going to refrain for the time beign from actually developping and explaining this idea, and perhaps if you haven't seen the movie then I've just really confused you. Perhaps if you have seen the movie I've still confused you, or maybe you agree or disagree. I think I need to watch it again. But it just strikes me as somewhat oxymoronic, given the presentation and the content. But are presentation and content different things? I don't even want to think about that right now. It's time for me to go to bed.
