Tracy Morgan has led an extremely difficult and interesting life, but the trouble is finding the truly moving segments in the book. Morgan's book goes in circles with the same stories and themes repeated ad nauseum to the point where they're nearly meaningless. I'd cut him more slack if it weren't for Anthony Bozza's name on the cover as well. At some point Bozza should have put the breaks on or found a way to streamline Morgan's story.
If you've ever seen the 30 Rock episode where the writers need to write Tracy Jordan's book in one day, this is the end result; an interesting life in a poorly executed package.
