I saw this movie in 3-D on a regular screen and really enjoyed it. Then I saw it on I-Max 3-D and enjoyed it even more! I felt like I was so close to the action--like looking through a window, like I could reach out and touch the characters! In my opinion the mixing of familiar themes into the plot: good vs. evil, advanced civilization plundering primitive civillization, innocence vs. world technology; trust vs. betrayal, added to the enjoyment for me. Acting was great. Choice of actors well matched for the characters. It was a little far-fetched in some spots; but I turned my rational mind off and just enjoyed the moment.
