Who do you think is an overrated writer in the history of modern literature? Why?

There is no first in literature, and no second in martial arts. A writer who I overestimated myself was Anai, the original author of Ode to Joy, River and Everything is Fine. When watching TV series, I thought the author's writing must be very good and powerful. After reading the original novel, I found that it was all a running account, and the top management was actually a screenwriter.
