Determining the quality of literature is subjective and multifaceted. A "good" piece often has compelling characters, intricate plots, vivid imagery, and thematic depth. It should evoke emotions, provoke thought, and resonate with the reader. I'm fairly comfortable critiquing texts, but it can be challenging when interpreting symbolism or cultural nuances. Genre and era influence my comfort level; I may feel more confident critiquing contemporary fiction than, say, Shakespearean plays, due to differences in language and cultural context.
