I enjoyed the film for a good story revolving around exploring a new world, new species of sentient beings, and the action of confrontation all in 3D. I also enjoyed the subtext of preserving the enviroment from commercialism in mining and exploitation of resources. Plus, the simple warning of any future human exploration of space when dealing with another sentient species who appears to be less advanced.
Smile, give chocoalte, and pray they don't find out human flesh tastes good.
