Final answer:
A story's protagonist possessing only good characteristics and no faults is a flat or one-dimensional character. These characters lack depth and complexity, and can be unrealistic and less relatable to readers.
Step-by-step explanation:
In literature, a character is deemed "flat" or "one-dimensional" when the protagonist exhibits solely virtuous traits without any discernible faults, rendering them predictable and lacking in complexity.
Such characters, epitomized by unwavering honesty, unyielding bravery, and unfaltering kindness, may appear unrealistic and fail to resonate with readers due to their absence of internal conflicts or flaws.
While flat characters can serve specific narrative functions, they often lack the depth and development seen in more intricate, multidimensional counterparts.
These simplistic portrayals hinder the audience's ability to relate to the character on a personal level, as the absence of imperfections and internal struggles can diminish the character's authenticity.
In crafting compelling narratives, authors frequently opt for characters with layers of complexity, contributing to a richer and more engaging storytelling experience.
