Couldn't appreciate the movie or the technology behind the movie, although I know that it was years worth of hard work and research, because of the 3-D (goggles). It gave me a headache within first 30 minutes. Wish the movie was in IMAX & no 3-D. James Cameron probably wanted to show his creation (Pandora) to audience in 3-D and I totally appreciate the grandness of planet Pandora. I also kept saying myself to take little bit of inconvenience, but it was just too much.
