Ingmar Bergman comes very close to camp in this 1977 study of life (or lack thereof) in the decaying Berlin of the 20s—how else to take exchanges like “Go to hell!” “Where do you think we are?” David Carradine and Liv Ullmann suffer mightily and at length, but the unmitigated anguish has no shape or substance, apart from pointing out that Nazis and their progenitors were not nice people. To that extent, it’s simply exploitative.
