Absolutely superb article, and I heartily agree. I was recently hired to write the screenplay for a short film (for a UK producer who now has to try and fund the thing). In my first draft, something bothered me about the ending. I left it to one side just before Christmas, and picked it up again a few weeks later with fresh eyes. The problem was immediately obvious: The dialogue in the last two pages simply told the viewer what they'd already gathered through the film as a whole, which is largely told in images. I cut the dialogue entirely, and suddenly the ending worked (and the producer agreed).

It's a bit like what happened with Witness, another of my favourite films, when Peter Weir cut the dialogue in the final scene between Harrison Ford and Kelly McGillis. It simply isn't needed. We know how each of them feel, because the film is image driven and the job has already been done.
