Simon entertains me through movies and tv. I wasn't as entertained by the book but I really didn't expect to be. Sometimes I think it's difficult for really funny people to be really funny in writing.
This is a memoir for Pegg (they keep getting younger - writing their memoirs) but he interspersed a pretty great piece of fiction with himself as the suave, handsome hero. The fiction story was more entertaining than the non-fiction.
Pegg is a nerd. Was a nerd. Probably will always be a nerd. He had a good concept of presenting how the nerdliness from his younger years morphed into work as an actor.
If you like Pegg, you will probably enjoy the book. I recommend the audio book though because his storytelling (of the fiction story) is quite .... enthusiastic.
