I can't remember the last time I was THIS excited for a movie!
I went to the "Avatar Day" event last August and saw 20 minutes of the movie in IMAX 3D and I was floored. Some of the CG was standard ILM-level stuff, but some of the visuals were unlike anything I've ever seen. I think the big difference is Cameron; the guy's an absolute master film maker and the way he frames each shot and incorporates the film's stunning look into its plot just kicks ass.
There's also a lot more going on story-wise than the 3 minute trailer shows, so it's best not to prejudge :)
I should shut up though; the last movie I was all riled up for was The Phantom Menace...
Still, my wife dragged me to see the new Twilight movie last night, so no matter what the next movie I see is, it will seem like a goddamn masterpiece!
