Just to compare, I watched the movie, also. I thought that the book was a lot better than the movie. the movie portrayed the characters a lot different than the book did. And I liked how the book portrayed them rather than the movie did. Also, the movie left some key details out that the book contained. The movie was just not up to par with the book, in my opinion.
I am Number Four, was fun to read. But I think that my next book wont be scientific fiction. Since most of my books I read are that genre, I think I want to branch out and maybe read a mystery with some cliff hangers. Or maybe even a inspirational biography about someone I look up to.
Probably my favorite character was the main character "John". He is a dynamic and round character because we get to see his full personality through his actions.
