The road movie is usually the domain of cowboys, crooks, drifters, and desperadoes. In other words, men. Thelma & Louise  is a road movie about women. Its feminine emphasis imparts a fresh twist to its familiar elements.
The Straight Story  is a glorious aberration. At a time when movies tend to dazzle with speed and style, it rolls along at a snail's pace, allowing us plenty of time to observe the changing sky and the flora in the roadside ditches.
