I was under the impression this would be more about Hurricane Katrina and the after effects of it but it's mainly about a prodigal flutist and her reactions to the wetlands before and after. Her friend who lives in the wetlands gives an idea of how the bayou has been in recession but he sounds a lot like the rooster from Disney's "Robin Hood" so it's hard to not focus on that similarity.
If the documentary had decided to focus more on the wetlands, that would have been fine. However, it starts to dramatize Hurricane Katrina and uses computer animation at some points to show havoc being wreaked. There are also a series of picture frames that show action happening in each of them. Usually, it's two off to the side with the same action and something else in the middle. It was not necessary.
The IMAX camera is best used here when it's showing sweeping overhead shots but unfortunately the movie needs more than just the shots and an attempt at one person's story and it doesn't deliver anything else.
