I must admit I didn't like this book nearly as much as Nothing Sacred. For the most part I could still hear Lewis Black saying it through, which has not always been the case with books by other comedians.
It's less a rumination on Christmas and more a rumination on where Lewis is in his life. Christmas makes Black extremely lonely. It's certainly understandable.
He's awfully hard on himself. You don't have to give up everything you own to be a good person.
I really love his Christmas morning ritual of writing checks to charities.
The book may be sad overall, but there are several genuinely funny moments. I laughed frequently.
