Straight Story
Seeing as Alvin never leaves the rural area, this gives him a wider space to grow. It seems that within the limitations of the city, one can only change their mindset and paths so much, whereas on the open road, the body and soul can expand virtually indefinitely. To me, the rural setting would pave the way for a much deeper growth and reflection than city streets. We see this in Alvin, who learns more about himself in meeting other people, than he ever expected. He learns that he has struggled and striven but can prevail each and every time. This is more acceptable in a rural setting and easier than on city streets.
