I've always felt that statements like "anyone who likes this is an idiot" or "you'd have to be mentally ill to enjoy [film]" are very misguided. In reality, people of equal competence and sanity can (and often do) come away from the same work of art with drastically different opinions. In fact, every individual person approaches film from a slightly different angle than every other person, and ones reactions to a film are generally a result of things like personal experience and worldview and aesthetic preferences and so on. Intelligence or sanity rarely have anything to do with it.

Edited - to reduce meanness.

You say all that Timec, yet you have no problem calling people idiots for interpreting a film differently to you, or disliking a film that you like. Seems a bit hypocritical.

I don't know which edition you've watched, but I found the audio on The Criterion Collection's Blu-ray to be more than adequate. I had no problem following the narration.
