Basically, this movie is Dances With Wolves with big blue Native Americans that fly Pterodactyls.
With that said, it is a good movie.
It is truly a cinematic experience though...the RealD technology was fantastic and truly groundbreaking...the eyes took a bit to adjust to what I was seeing, but after that, you truly immersed yourself. I thought, more than anything, the idea of layering the shot in the way they did, did more for the film than anything done in film making in a long time. It made what should have been a VERY visually busy film (to the point it deters from the film) into a film visually stunning and completely immersible. Cameron surely outdid himself with this level of technology in the film. Truly a benchmark in film making. I fear though, this may overrun Hollywood and not for the better. This technology is going to generate way too many bad flicks, if it already hasn't.
As for Sam Worthington...he is your new it-guy in Hollywood, for sure.
Overall, it is tough to grade the film...as an experience in the theatre, its up there and you can't really pass up a chance to see this in the theatre, but on the other, it is tough to see how well they did in terms of film making outside of visuals...storyline? Well...its been done before, but, after taking film classes, most films are ruined anyway, as they all follow the same pattern with the same basic sets of storylines...this one, we've seen before many times, so, how well did they pull it off? I'm not so sure, as I was too busy watching the awesomeness in 3D.
I wonder how the regular, 2D experience for this film plays out...I will make sure to watch this in 2D as well...should give you an idea of how really good/bad the film is.
