The Vanishing is a 1988 Dutch horror film. Very suspenseful. I'm not claustrophobic, but this film made me feel as if I were.
Moria gives it a great review, calling it "an excellent thriller" and praises its genre-bending plot, saying, "The elliptical nature of the plot and the subtlety of the clues laid out is breathtaking." Best-Horror-Movies.com closes its review with this: "The greatest thing about this film is that it really can appeal to so many people. It’s a horror movie for people who dislike horror movies and a horror movie for people who can’t see enough horror movies. In that way, it’s quite brilliant." Time Out calls it "An unforgettably chilling psychodrama". Roger Ebert gives it 3 1/2 out of 4 stars and calls it "a psychological jigsaw puzzle, a plot that makes you realize how simplistic many suspense films really are." Rotten Tomatoes has a critics score of 100%.
