The movie is all about belief in the existent of the guardians, where these belief give them power to protect the young and innocent one. Plot started to build up with Pitch, the evil nightmare trying to regain control and to rule the world with fear and nightmare.
This is where Jack Frost, one of the main character come into picture. It is a simple yet familiar storyline without any twist to the story. The part that amaze me is actually the CGI and partial of its 3D effect. I guess to truly enjoy the visual effect of this movie, you're advice to sit nearer to the screen.
