And, a strange movie it is. But, really well done. If you liked Eraserhead you will like this movie. The plot is fairly simple -- "Old friend" wasn't really that much of a friend. No, this movie is all about the mood. The melancholy. I would watch it again in a minute just to see the absolutely perfect Mid-Century Modern house and furnishings. Whoever did the set totally nailed it. Top-to-bottom, accurate Mid-Century Modern.
Is it slow? Yes. Does everything make sense? No. But I don't think that was the point of this movie. If you need a tight little average story with an A-Z typical plot, this is not the film for you. If you like a film that conveys ambiance and disturbing, vague suggestions of a back-story, then you'll probably like it.
