The video effects are striking for a 1963 film. The dead man in the house remains genuinely impressive, and the photography and editing are consistently strong, to the point that the film still provokes curiosity about how certain shots were achieved.
Some acting moments are dated enough to be unintentionally funny. I genuinely laughed at a few scenes. That said, the hysterical mother with the children delivers an outstanding performance as a secondary character, one that feels underdiscussed and far more effective than many of the leads.
