As I titled this review, I realized Cameron had borrowed from many past movies to create the plot and provide the dialog, and not always in the best way. ("We're not in Kansas anymore" - are you kidding?) Nonetheless, his movie is a cornucopia of color and panorama, and for this is worth seeing. The masking of boundaries between human and avatar is excellent, which makes the avatars more real. The 3D effect is not intrusive, and would probably be even more effective in IMAX. My ultimate test for a 2 hour and 40-minute move was passed - I did not look at my watch even once.
