This "speculative documentary" uses reels of historical footage to ponder what life in America might have been like if Kennedy had survived his 1963 assassination. It's all based on a popular lecture by Brown University professor James G. Blight and comes to some rather obvious conclusions (most of them aimed, tacitly, at the Iraq War). However, scattered amid this intellectual game of "What if?" are some fine, historical nuggets. Chief among them are Kennedy's sharp, civilized press conferences, which emphasize intelligent diplomacy over overt hostility.80 minutes Unrated.
