Just been thinking about this over a (very boring) class trip:

What if it's not a coincidence that the big Na'avi settlement was directly on top of a massive unobtanium deposit? They do live inside of a massive (bigger than most of the others, in fact) braintree, after all... and the braintrees are obviously capable of sensing electrical and magnetic fields... like those generated by unobtanium! The other Na'avi site (the huge I/O willow grove) is located at the center of another extraordinarily magnetic area.... maybe the humans can't just go somewhere else because all the significant unobtanium deposits on the planet are already being used... by the braintrees! I'm too lazy to crunch the numbers on this, but it seems that without some very conductive medium, the trees would have a hard time mustering the voltage needed to send signals across a large moon. I originally envisioned some sort of organic dynamo using the deposit as a power source for the trees' electrical communications... but that's pretty ridiculous. It makes more sense to me for the trees to leech shallow unobtanium up through their roots for making some kind of superconductive pathway within the root system that makes it much easier to communicate at low, biologically-producable power. Maybe the Na'avi are just there because the trees are bigger and make a nice place to sleep at night, or they actually engage in some sort of symbiosis with them..... see below.

Consider that Aiwah's ability to control the higher animal population of Pandora could easily be applied to mating habits... which means controlling which traits are passed on to the next generation of banshees or lemurs or whatever....considering that the trees have been around for millions of years in one form or another (they cover the entire planet, have vast reserves of memory, apparently one single consciouness, and they must have outcompeted the non-brainy tree species: it's doubtful that an organism that large/powerful/smart could be driven extinct by a regular old ELE) it becomes possible that Aiwah controls the evolution of Pandoran species, and created the Na'avi. Why? I don't know! Maybe to "service" the network or protect it in some way (as they do against the humans).....maybe as a means of gathering information (the Na'avi do, after all, routinely "back up" their memories in the willows).... maybe as some sort of companion species (I'm not sure if a giant vegetative brain that has never encountered sentient life other than itself would get lonely or not).... or maybe just because it wanted to see if it could.

Yeah. It was a REALLY boring trip.

there's also part 2..Star Wars review, Star Trek movies as well..good entertiament

i heard the first 3 secs of video and i knew the guy was a joke, and not worth listening to

people who's wives hair can be destroyed by a ceiling fan and who have to help take the wheels of their richest relatives new house, dont have the capacity to have valuable opinions

well, when i need to know how to live in a box, ill be sure to ask one of them, in the meantime, im feeling sick because of how much of a twat that guy was...

i realise part of it was for humour, but then hes taking things about the movie and twisting it (very much in the same way religion does) to have a negative connotation... like the big eyes and cat nose was designed to evoke sympathy... well, no shit? also, they're pretty? in todays society, thats the way it works, if its pretty, people like it...

and the comments he made about district 9? bleh, as if they DIDNT beat you over the head with the message?

grrr, ignoramous' like him are an insult to intelligence and make me sick to be human, and related to such a sack of dumb...

Important question: why did  the humans attack on ground at all in the final battle? The point was to bomb the Naavi to death, not storm their homes; any thoughts on why a ground assault would have helped in any way, especially since the natives didn't have any kind of anti-air weaponry or tactic from the ground.

I really want to watch this thing..... in the 10 minutes before I go to school.... any chance we can get bullet points or something from somone with more time on their hands than me?
