Very effective chamber drama, if you can accept the fact that one of the four characters is, I believe the medical term is, cuckoo. I’m sick to death of stories with characters who are vaguely and eloquently nuts. But Bergman didn’t know this in 1961 just like Tennesee Williams didn’t know this when he wrote Glass Menagerie or Streetcar. The movie is beautiful to look at and very evocative even if my mind wandered a bit during the midde a little. What is key is that when I wandered I wasn’t thinking about my laundry, I was thinking about the little house they were staying at, the clothes they wore, their faces, what was really going on with the brother and sister, etc.
