I say that sketch films, because they are so wildly variable in quality, are rarely worth watching, and this one is no exception. There are perhaps two sketches that hold interest:Gustav Molander's version of Maupassant's story The Necklace, in which Bergman and Bjornstrand play very well in a restrained classical style, and Jorn Donner's little comedy of two lovers who can't quite get down to doing the act they intend. I didn't realize how well Harriet Andersson can do comedy; she really gets in the groove here.
For the rest, it's easy to see why these directors made no name for themselves outside Sweden. I was particularly annoyed by Sjoman's silly, childish sketch with the man trying to hide a young black woman from his wife in his apartment.
Finally, I acknowledge Ingmar Bergman's supremacy in the film industry, but his grainy home movie is not in the least interesting. You find the impulse to fast-forward through this one is irresistible.
