Despite being a huge fan of the show, I couldn't really get behind this book.
I did enjoy most of the cast interviews and their thoughts on the characters they play but the information on production budgets, catering and scheduling just ran so dry. Normally, I'm pretty interested in this stuff - I really enjoy watching the segments that are a part of the season collections but it just didn't really hold my interest.
There is one bright spot which credits at least one of the two stars - the foreword, which was written by Hugh Laurie, was supremely entertaining. If anything, seek it out for that.
