Sarah, I tell people to just tell me the end of the movie. I never want to be in a dark theater again waiting for supernatural occurrence and be treated to the ending of “Don’t Look Now.” Yes, it was full of signs and portents, a sightless woman seeing, red hoods and skin cut on glass, flowing blood. A portent reader straight from the woods not accustomed to screens and artifice never saw it coming. The real portents and conclusions are seamless, as natural as twilight moving into night and easing back into dusk. The ones we construct and splash in the outsize are the nightmares.
