I always appreciate listening to books read by their author. You get their own inflections and meanings of things, and they invariably make their own additions to whatever they're reading.
It's definitely a good reminder that Wil Wheaton is NOT responsible for the decisions made by and for Wesley Crusher on Star Trek, and certainly not deserving of any personal hate.
Still, the story definitely made him sound awfully self-centered and, at times, just as whiny as Wesley. Sure, it's a memoir, so it's going to be "all about me", but it seemed overly so. It was certainly fun to read about all the behind-the-scenes stuff in both Star Trek and his personal life, learning about a struggling actor who doesn't just get roles handed to him. I also felt sorry for the way he was treated by the management at several points in his career.
