I. The film adaptation of the popular Diary of a Wimpy Kid book series is amusing and witty, though not as good as the original books. It raises important issues about adolescence.
II. The film follows Greg Heffley as he starts middle school where he is one of the smallest kids. He tries to become popular by changing his best friend Rowley, but ultimately Rowley becomes more popular by being himself, teaching Greg an important lesson.
III. The actors who play Greg and Rowley capture the characters' lack of coolness, and the older brother is also well-cast.
