I do not know if the original books have the campiness that the movie and the manga have. This makes it more enjoyable and the images fun. Characters are likable and relate-able. The fact that Darren Shan named the character that is a vampire after himself is just awesome. I knew what was going to happen as I saw the movie and I believe this second book end is where the movie does. Although some parts are left out of the movie. I love the friendship with the fellow Cirque Du Freak characters that Darren has immediately.
I do want to read the original books to see the difference from the mangas. I always got the feeling there was a different feel to them compared. The manga is fun, exciting, and creative.
