This movie is a very superb and well made thriller. Im surprised it got such a low rating considering its entertainment value. From the beginning the movie starts us right away with the premise. From there we are taken through a very suspenseful ride in trying to figure out wether a woman is right in suspecting her husband for murder, accusing the wrong man for murder, or covering up for the murderer. As the movie develops, different clues keep popping up and were made to really think and engage. As the movie gets closer to it's climax, the suspense gets more intense. The acting is very convincing and I found myself truly sympathetic for Martha in her efforts to figure out the truth. . Add the great camera work and shadow effects, this movie is now on my list of favorite classic movies. Don't let the other users discourage you, they are simply trying to compare the movie to other films that are not meant to be compared to. Watch it for yourself and see how fun the ride truly is.
