1. Must see in 3D only. 2. Do NOT go for the story line, which is predictable, simplistic, and has the unavoidably preachy morality play comparables to modern society (war for oil; treatment of First Nation indigenous peoples; etc.) 3. DO go for the 3D effects, the color, the imaginiation, the total visual experience; it is the best I've ever seen. 4. I've heard that people susceptible to motion sickness should not see this ... not true. I suffer from this and had no such problem. I give it 4 of 5 stars.
