Didn't realize this was by an 'artist' or wouldn't have bothered. The story had possibilities - an American architect comes to Rome to oversee an exhibition. His much younger wife starts an affair and his life unravels. However, the Italians he interacts with are caricatures, and we don't know why. Why does his wife start the affair when she was obviously happy at the beginning? Dennehy gives a very good performance of a person of whom we don't get to understand.
Many of the iconic sites of Rome are shown, but the photographic quality - at least of the version I saw - was quite poor.
In short, this film is pointless and not entertaining. Was the director depressed or just trying to depress us?
