I would disagree, the first viewing of a film gives you an overview of what is happening, whereas subsequent viewings will reveal the more subtle things. I think this is because you are not trying to concentrate on what is going on so much you can see different things, I was just thinking this morning that I would like to watch Donnie darko again, it took me a few watches to really understand the point of the movie, though that was 7 or more years ago.
