I know most of us have seen it, but if you haven't (or it's been a very long time), this is your assignment this weekend. Watching this film with the reverence that it deserves will leave a lasting impression on you.
I don't know where you got that read, but I've never heard anyone say anything even close to that before and I've read about and been involved in analysis and discussion over this film for years. Everyone is, of course, entitled to their own interpretation of any art work, but this is one of the simplest and least intuitive I have ever heard.
