Hitchcock used an example to explain the difference between surprise and suspense. If people are seated at a table and a bomb explodes, that is surprise. If they are seated at a table, and you know there's a bomb under the table attached to a ticking clock, but they continue to play cards -- that's suspense. There's a bomb under "Dont Look Now" for excruciating stretches of time.
I was expecting this slow-moving movie to descend into routine shock and horror movie,but it doesn't. Most of the movie is all waiting, anticipating and dreading. The jolts that come about midway are of a similar magnitude to movies such as Sixth Sense or The Exorcist.
The film is slow moving, but it manages to expertly linger to create atmosphere, a sense of place, a sympathy with the characters, instead of rushing into cheap thrills. Dont Look Now stands as one of the most beautiful and moving "horror" movies in the 1970s...even though it is not really a horror movie; it's more of a psychological thriller.
As it gears up for a truly unexpected, emotionally draining finale - destined to please or frustrate depending on how nihilistic you like your horror - this elegant ghost story ignores genre conventions to deliver a touching tale of motherhood and fatherhood, love and what may or may not lie on the other side.
