James Cameron has proven himself as a worthy director. Best character development: Sigourney and Zoe. Jake Sully, chosen one, is portrayed with emphasis as a warrior. It is questionable if his fight is for his love for spiritual binding of Na'vi & their deity; or the usual; "boy meets girl-boy wants girl back." This is evidenced by scene where interacts with tree of souls. He is not sure she can hear him or not, but asks for some help. His character in that scene would be more developed if he had expressed /reflected more of the spirit of the ways/beliefs of the people....deeper. Other than that, for an age-old story, it was richly done; and the IMAX experience enhanced the technology. It is definitely worth seeing!
