The 1971 movie (which includes- memorably- Art Garfunkle) is somber and pining... probably because the directors wished to use it as a vehicle for their Vietnam-era anti-war sentiments. I don't think that is quite how Joseph Heller intended this book. Don't get me wrong: there is pain and tragedy in these pages, but Heller doesn't hit you over the head with them as artlessly as the moviemakers do. The book contains many light moments, where Yosarian's pain at the chaos of war is tempered by feelings of comeraderie for the quirky antics of his companions. I would give the movie 3 stars, but the book definitely 5.
