As a Marx Brothers fan for over 30 years, I harbor no illusions as to what an ornery and mean-spirited man Groucho could be. He was never comfortable with himself, and, unfortuntely, he passed along a lot of that insecurity and misery to those who were closest to him. He was also a caring, literate, and liberal man with a worldview and wit like noone else. Yet, according to Kanfer, Groucho's entire life was a failure. ALL the movies are terribly flawed, no generous deed was performed without a sinister intent, and the fact that he was a greater comedian than writer negates all the success he had in the latter area. This is more a vendetta than a book. Kanfer is more mean-spirited than Groucho ever was. In addition, his idea of research is to read every other book on the subject and then weigh in with a third-rate behavioral analysis. I'm currently reading Simon Louvish's new bio of all the Marx Brothers, and, so far, it is a breath of fresh air (and well-researched to boot). If you want to read a bio of Groucho, seek the out-of-print Hector Arce book. All things considered, Groucho was a very great man, but you'd never know it from Stefan Kanfer's tedious character assassination.
