Final answer:
The trend opposite to the late 20th century's linear storytelling and spectacle-like films is represented by 'Nonlinear, complex narratives', which involve stories told out of chronological order, often through techniques like flashbacks or symbolic imagery.
Step-by-step explanation:
The last quarter of the 20th century in film saw two distinct trends: linear, easy-to-follow stories and films that were heavily dependent on spectacle, often featuring major special effects. The options provided in the question seem to refer to the trends that characterize storytelling in films distinct from the mentioned trends of the late 20th century. Option A, 'Nonlinear, complex narratives', contrasts with the linear storytelling trend, indicating a shift towards more challenging and intricate story forms that do not unfold in a straight line. This form, as articulated by the information provided, involves flashbacks, vignettes, and can jump back and forth in time, giving rise to multifaceted narratives resembling less traditional and more innovative story structures.
Considering the provided materials, which discuss the evolution and diversification of film genres as well as the stylistic and technological developments over the years, we can deduce that the correct trend opposite to linear storytelling and spectacle would be nonlinear, complex narratives, marked by stories that do not follow a direct chronological path and often incorporate innovative storytelling techniques such as flashbacks or symbolic imagery.
