Not too long! Beautiful. I enjoyed all 168 minutes. I like watching Sandrine Bonnaire walking around, having her morning coffee, and Rivette shoots her beautifully, making what could have been an ordinary thriller into a character study. She also starred in Rivette's JEANNE LA PUCELLE, 5 & 1/2 hours, and it was great. Granted, I had the luxury of watching these films in pieces, half in the theater, and half at home.
