What I really like about "The Autobiography of Malcolm X" is Malcolm's honesty. He is always upfront about everything. When he talks about his times of being a hustler, he tells all the details of his hustles. He includes how he was a drug dealer, a burglar, and more. He even gives advice through the eyes of a burglar: to protect your home against burglars, leave the light on in the bathroom. He speaks of his constant drug usage and how he was "trigger-happy." All of these details make Malcolm's story much more memorable and realistic. We see the whole story, not just parts that make someone seem better. We see what Malcolm has come from and what he's gone through, which has all led him to the person he is today.
Malcolm's attention to detail also helps complete his story. He remembers where he learned what in which book. He remembers big chunks of his speeches. He describes what he felt during each situation. He also includes the story of Mr. Yacub. While I don't agree with the story (one shouldn't blame an entire race for all of one's problems and not everyone from that race is the same), it's one of the sections I remember most in the book. It's full of information and sets the basis for Malcolm's religion.
In general, Malcolm X is a talented writer. The way he tells his story interests me and I want to see what would happen next. The reader gets a good idea of what led Malcolm to become who he was.
