Yes! Yuck! Also the horrible perm and sleazy polyester wardrobe on Diane Keaton as Kay Corleone--their stylings were totally out of whack for both of their characters.
Nevertheless, I'm one of the few people on earth, apparently, who loved Part III just as much as Parts I & II. I've been to Sicily and inside the Vatican, and those scenes had great meaning for me. Loved Andy Garcia as Michael's nephew, and also loved Sophia Coppola in her role as Michael's daughter. And I'm a fan of the Irish actor Donal Donnelly, who played Archbishop Gilday. (He was also brilliant in John Huston's haunting film of the James Joyce novel, The Dead, starring his daughter Angelica Huston.)
The plot of Godfather Part III foreshadowed the messy goings-on that would later occur with the Vatican Bank. Puzo must have been clairvoyant.
