The guys at TRS (my favorite show) summed up the experience pretty well
And I think this is the behind-the-scenes hulu [2] part they are talking about.
Make sure to see it in 3-D… or “REAL-D” as they call it now. And not at home in HD — I saw it in IMAX.
The 3-D is pretty close to reality (or at least a thrill ride) – especially the first 5 minutes – you definitely feel ‘plugged in’ (as if you are an Avatar). I saw no one in my packed-theater get up for a bathroom break during the 3 hour movie — this movie can be pretty hard on the body 
worked up an appetite 
worked up an appetite The framerate seemed to get a little buggy/ghosty when small objects (like those pesky spores) are moving from the furthest depth and moving in closer at you (especially fast-moving spores). It seems like there are 5-8 layers of depth and James Cameron probably had to pace the 3-D action just right so no one would get sick. But you can definitely keep up with the action and keep track of what’s onscreen (vs. say Cloverfield/Dark Knight/Transformers shaky cam). And the visceral emotions and splendor the movie evokes makes me want to travel back to the land of Pandora right now by myself and see it a 2nd time (love it like when I saw Jurassic Park 1&2 and hoped it could exist for me to study and interact with — btw, the animals in Avatar remind me so much of Littles).
Avatar Is Like The iPhone Of Movies. I’ve seen Avatar twice now, which is saying something when you’re talking about a nearly three hour movie that was released 36 hours ago. – TechCrunchAvatar is the kind of movie that you’ll want to experience on a giant screen. And as disgusting as it is for me to say it, this $300 million monstrosity is exactly the kind of film that Hollywood needs to save it’s rear end from a future of $1 Redbox DVD rental kiosks. – SA Forums
I was told there are two types of 3-D glasses: one for IMAX 3-D and one for digital theaters (called REAL-D). I noticed the movie screen looks much smaller when you put the glasses on (more focused/sharp and detailed). I’m interested in seeing it in a regular-sized digital theater which uses the different type of blue 3-D glasses — probably what the movie was meant to be seen in — most films aren’t shot with an IMAX camera).
Intially, I was very skeptical about the movie after seeing the trailer. Disappointing memories from seeing FernGully as a youth came back to me — a movie which most definitely was not a Disney-quality film despite Robin Williams presence (I think it went direct to VHS, where it belongs). But Avatar was so visually impressive (especially those spore moments) that it was able to bring the “audacious” force that I’ve only experienced in an anime or a videogame to the bigscreen (the mainstream, as a popular blockbuster)… something I wondered if those in my theater were familiar with, if not, what a treat for them(!)… Definitely something mind-bendingly appropriate for a kid’s imagination. This movie will do well in theaters, from what I expect to be fanatical word-of-mouth.
Never before done visually, a friend raised a point where this could be where humanity is be heading: paying for experiences ($12.50 IMAX ticket+$2.00 for 3-D glasses) that can only be granted by big box publishers (20th Century Fox in this case). We’re getting there — I was walking into the grocery store earlier today to see people single-file in line in this dark, wet, and dreary weather for those $1 Redbox DVD rentals. Kind of reminds me of that 1980′s Twilight Zone episode “Dreams For Sale”
It is something of a disappointment to take off the 3-D glasses, ‘awake’ from Avatar, and see people walking out of the theater into this dark, wet, non-winter-wonderland weather. It is worth it though – the scene where spores are falling down especially reminded me Studio Ghibli’s spore-scene in Nausicaa (4 minutes in), of which I’ve never seen the ending to.
But Avatar is fully realized — no imagination required — you feel like you’re really there.
