first off, i think they tried too hard to make it 3D, the previews of alice in wonderland and 3D piranha's were much more so pop out in your face then avatar.
i would have to say i enjoyed avatar. it was an epic movie in itself in a try to be like star wars kind of way. the storyline was decent, and flowed in some resemblance to kevin costner's "dances with wolves."
the feel had disney's "tarzan" and "the lion king" -esk to it. with the worlds, and trying something else other then what we are used to in it. but if i lost my legs, i, too, would give up this technology filled society we live in.
now here's the thing that bothered me about these fantasy movies.... originality. there really wasnt too much original cool stuff in it. the linking to avatar thing.. reminded me of assassin's creed or angelic layer. its been done. the military forces' air vehicles were clearly from halo, with weapons from gears of war. the glowing forest that kept lighting up. final fantasy.
then there's being attacked by someething "wild" you fight it, weaken it, then "capture" or "bond" with it. its pokemon. had to admit that those flying mounts, looked like lugia. and that near the end part where jakesully got the ultimate pimp ride? total EPness.
i did like the idea of how they "linked up" to everything in their world tho. that was totally cool. hope thats not how they "mate" and get into each other's minds.
