Great idea, but this project was miss lead by the title.
This production starts off in the Grand Canyon then gets into water supply's of the world.
It's a shame they went about it in this manner.
Some 3D shots were shot incorrectly, flat against the river. Helicopter shots don't normally work well in 3D, one did.
I learned nothing about the creation of the Grand Canyon in the production and not enough about anything to do with the Grand Canyon.
Over all this project would be considered a dud.
