I really enjoyed this "documentary." The story is told through the lens of a fictional family who has moved to a suburban neighborhood outside of Toronto from a more urban area. They made the move to get a bigger house with more space and to hopefully give the kids a better life. Throughout the movie, all of the major issues of urban sprawl are covered.
The family psychology moves from euphoria to uncertainty to misery throughout the course of the film as they discover that their move to the suburbs is not making their lives easier or happier.
If you would like to see a movie that gives you a primer on sprawl, check Radiant City out. You will definitely see a lot of similarities with Atlanta since we unfortunately are a sprawl city.
