Laura Dunn's film about the dangers of overdevelopment, and the effects it can have on the environment, is the type of documentary that manages to knock the wind out of you as you watch it. This is because she manages to hit the nail on the head of the "how can you not see this?" correlation between cause and effect. Dunn interviews key people involved in the political overdevelopment in Austin, Texas that was bitterly fought between developers like Gary Bradley and environmentalists in the Save our Springs alliance. While people talking about the dangers of overdevelopment are not new, Austin serves as a perfect window into the debate, because of Barton Springs, a natural spring-fed pool near downtown Austin that has served as a public swimming hole and park since the early 1900s.
