I did not read the book and I enjoyed the movie. Hanks played an interesting character, a mix of antagonist and hero. The puzzling through the symbols' hidden meanings, the chase scenes, the old world beauty of Rome and the history, for me an engineer, overcame the silly science concerning anti-matter. But two in my family read and enjoyed the book. For them the movie, at least in part, disappointed. I am a Protestant; I wonder what Catholics thought of the movie.
