What term describes something that greatly affects people's emotions?

The term that best describes something that greatly affects people's emotions is "Dramatic." In literature and performance, drama often aims to evoke strong feelings like joy, sorrow, fear, or anger in its audience. The dramatic elements, such as conflict, tension, and heightened emotion, are integral to engaging an audience emotionally and can lead to powerful reactions.

While "Amusing" pertains to humor and might evoke feelings of laughter or light-heartedness, it doesn't encompass the broader emotional spectrum. "Ironic" refers to a contrast between expectation and reality, which can lead to a more subtle or intellectual emotional response rather than a profound emotional impact. "Comic" similarly relates to humor and amusement, lacking the depth of emotional influence that "Dramatic" embodies.

Thus, the term "Dramatic" captures the essence of something that profoundly influences people's emotions, through elements of storytelling and expression that resonate deeply with audiences.
