Query: Are you serious?!

After reading the DaVinci Code I thought that Dan Brown had something going for him and was suckered into reading this book. The historical and scientific accuracy he uses to beef up his plots are his only saving grace. Other than that, I have a hard time believing anything that he writes. It's fiction, I know. But I just kept having this feeling that this book would could easily turn into one of those absolutely unrealistic action movies with Tom Cruise or Harrison Ford where jumping out of an exploding helicoptor at 3000 feet without a parachute doesn't kill you. Better luck in the future, Dan!
