Angels and Demons is a movie for the unbiased, and unoffended, because the major theme in this movie is the battle between religion and science. Ron Howard does a very good job directing this film, he uses color, and excellent lighting effects to show the mood of the scene. The cinematography is also very good with the lighting and angles to add mystery, and intensity to the scene. If you really enjoyed the book like myself, prepare to be disapointed. The screenwriters took out some characters, and changed parts of it to keep it under a 2 and a 1/2 hour run time, but i got really mad when they took out Leonardo Vetra, The BBC Reporters, the romance between Robert and Vittoria, and they changed the ending a bit, and they didn't fully explain why these events happened, and the whole thing about the pope's son. All in all this movie is entertaining, and well paced, but it will do little for the uninspired, and get the book lovers angry.
