I will admit Cameron isn't the best storyteller/writer. He does well enough to get my attention but not so skillfully that I want to praise his storytelling.
But Avatar tapped into a lot of things I'm keenly interested in - both in terms of ideology and visuals. And I love well done 3D (cue the old Viewmaster toy as a kid story) so it was like a perfect storm for me. I really, really liked Avatar.
Now, seeing Avatar in 2D (which I did two out of the three times I saw it at the theater), I still enjoyed it very much... but the high flash of 'magic' wasn't there. The one that evokes a childlike wonder and awe at something that captivates me.
I also watched it again on DVD and still liked it quite alot. Not as much as in the theaters but the story and the music still do it for me (although liking Horner is easier the less one listens to his other scores. I watched some other movie he scored recently and was disappointed by how much the score to that sounded like the score to Avatar. It was easier to like Avatar when it sounded 'fresh')
Then I caught parts of it on a small screen tv in a motel and was struck by how much the whole movie looked like a cartoon. Like a well done Saturday morning cartoon. I don't mean the story was any worse for me. But all the magic of the movie had been sucked clean out of it. When I watched Avatar on the big screen, I *believed* the Na'vi were real. I mean, intellectually I know they aren't. But conceptually, I completely bought into them as actual, real beings. On the small screen, that wasn't happening.
But that doesn't diminish the movie in my eyes. It just tells me how much I value magic in my life. We all find magic in different things. One way I find it is in 3D and/or holographic images (I also collect lenticular items). I love glow in the dark, as well. I loved them as a kid and I didn't let or make myself grow out of that as I aged.
It also kind of explains, I think, some criticisms I read from fans about some movies. Those of us who saw the LOTR movies on the big screen, many of us multiple times, saw those images in their intended display. We then might have watched them on DVD with, perhaps, good tv set ups.
But now we have multitudes of people watching them for the first time and maybe the only time on commercial tv networks. Maybe they're cropped. Maybe their cut for time. They surely have interruptions for commercials.
It would take a powerful story/movie to maintain any 'magic' with that working against it. I love the movie Chocolat. (Depp and Binoche) It was on commercial tv on day as I worked on the computer and so I watched it. I was appalled at how badly it was cut. There was no magic and nothing that would have made me sigh with pleasure or recommend it to a friend.
So when one of the LOTR movies plays on TNT and we get an upsurge in troll posts at imdb, I kind of almost understand why. Someone watched the movie for the first time in this handicapped format and, after hearing what a fantastic movie it was from everyone in the world, wondered 'hun? why the love for *that*?'
