one of the reasons i love the show is just how complex it truly is. It does a great job of showing different points of view. Most of the "bad guys" aren't bad, they are flawed people and you can disagree with them. best written series (ATLA & LOK).
I think this all the time. Try going in pitch black with a picher of water, a flashlight, and a bowl. As you pour the water in to the bowl shine the flashlight across the water. It will move sightly with rhe light. Water Bending!
