Ok since the six grade I adore the book and I absolutely love the movie too!! Shailene Woodley was such a great way to protray Tris/ Beatrice. She is just overall a good actress. She has good emotion that is overall great and you are dragged more to the story and she is leading the story. As for Four/Tobias he was carried out by Theo James. As a actor with a accent, he does a pretty good job at hiding it He also comes off as a tough guy that he looks like in the movies. He is a really good actor and is right for action movies and pulled off any character.
