Use the theory of Feminism to analyze it. The results confirms to be walking a fine line between critical self- insight and obsessive self- importance and insists that a lot of Elizabeth's own experiences can make the readers especially women learn to be stronger and more independent. Besides that the novel Eat, Pray, Love can have a heavy touch on the readers. People becomes more materialistic and always pursuit the worldly happiness in modern time. Eat, Pray,Love is also can make readers learn to respect other cultures. While the strengths of this novel are the unique format, the simple language styles which can make the readers more acceptable, the flexible use of foreign languages, and the cultural diversity.This novel also has weaknesses such as the viewpoint in subjective way and the plot in complicated way.展开更多
