There has been so much build up about the movie so expectations are so high, kinda hard to live up to for anyone. I'm excited about it though, hopefully I can find a place where I can watch it in IMAX 3-D, that would be cool.
Early reviews do say that the film is visually stunning...but lacking in story. Reminds me a bit, actually, of the early CGI movies that had some cool and new (at the time) effects, but not much of a story. Twister comes to mind. The Abyss was another - though the director's cut did add a lot.
If this catches on, we'll probably see a few others like this and rushed attempts before we see it used successfully, a la LOTR.
Simplified, this is the equivalent of two cameras strapped together, each providing a slightly different perspective on the scene, mimicking the way human eyes view the world in three dimensions.
the entire screen has depth, taking on the appearance of a window through which the viewer is watching a 'world' on the screen, with a distinct foreground and background, rather than a flat, moving painting
