Book Review: The Hitchhiker's Guide to the Galaxy

I read The Hitchhiker's Guide to the Galaxy.  It was funny.  It was the 25th anniversary addition.  The first half of the book wasn't the book itself.  It was just 90 pages of hype talking about how great the book was.  It was interesting but it set me up for a let down.  

Also the book didn't have any character humor.  It just had funny idea humor.  I liked it, but some character humor would have been good.
