Many people argue about Agee's complex text. The entire body of Let Us Now Praise Famous Men is written in a kind of highly emotional euphoria in which Agee combines his own thoughts and perceptions with exhaustive description of the world around him. His intense feeling causes the writing to be, by conventional grammatical standards, virtually unreadable. Once the reader gets past his chapter-long sentences and widely varying themes, however, the book emerges as one of the greatest written accomplishments of the 20th century.
While the nominal subject of the documentary is an in-depth exploration of three tenant farming families during the Great Depression, the real project (and Agee himself admits this in his remarkably confessional prose) is the documentation of his own experience living with those farmers for several weeks--sleeping in their vermin-infested beds, eating their home-cooked food, and interacting with them on a human level. In addition, Agee self-consciously writes the text and explores the act of writing, both during his stay with the farmers and several years later, when he completed the vast majority of the book.
The final product is a patchwork book pieced together from Biblical prayer, Evans's photographs, Agee's flawless descriptions (which, in several cases, may be more accurate than Evans's probably manipulated prints) and meditations on writing, poverty, art, and day-to-day human experience. Two things make this work remarkable: Agee's honesty (he never claims to be objective or non-judgemental) and his innate talent for description. I approached this book with an open mind, and found it to be one of the most thoughtful and rewarding works I have ever read.
