Wonder is the story of Auggie Pullman (Jacob Tremblay) a boy born with severe facial deformities as he goes to school for the first time in fifth grade. Middle school is probably the least forgiving environment he could be entering, as anyone who has ever met an eleven year old could tell you, but he has a strong support network with his parents (Owen Wilson and Julia Roberts) and his sister (Izabela Vidovic).
If the story had only focused on Auggie it would have been good, but what set it apart was that it branched out. A lot of time is devoted to his sister, Via, as she is also facing a tough transition in her life as she begins high school. She is used to having to take care of herself because Auggie requires so much attention and she is able to put her own problems on the backburner to be there to support her little brother.
They also look through the eyes of some of Auggie and Via's friends to see how Auggie has impacted their lives. This really helps the viewer connect with the film and really makes it work as a engrossing and heartwarming picture.
