The movie's two and a half hours run the gamut from humor and charm to tragedy and poignancy. Although epic in length and symbolic in treatment, the movie never loses sight of the intimate love story at its center. The relationship between the childlike Forrest (Tom Hanks) and the disillusioned Jenny (Robin Wright) can be seen as an allegory for America's loss of innocence from the 1950s to the 1980s, reflected by pop culture and socio-political events. Rock and roll, the civil rights movement, Vietnam, Watergate, and more are touched on, sometimes seriously and sometimes satirically.
