Except the part where the oxygen poor atmosphere feeds flames.

Or the part when the Colonel is on fire and the flames go out when he moves to an oxygen rich environment instead of causing him to practically explode.

Or the part where an oxygen deprived brain suffers no consequences.

I'm sure there were more, but it's been a while since I saw it.

So what you are saying is that on a planet with four-winged dragonbutterflies and every creature has a natural neural link (which, if it gave an advantage survival-wise over not having one, could happen over a long period of time, even the seemingly universal compatibility), there is absolutely no possibility that there could be elements in the air that burn with little to no oxygen?

When does he go into an oxygen-rich environment? Could be it was supposed to be turbulence blowing out the flames, which weren't exactly huge to begin with (although I would have loved to see him get engulfed and killed by the explosion he jumps out of, just for a change of pace).

I'd say the brain thing can be handwaved with 22nd century medicine, considering that they seem to be able to genetically engineer a creature out of DNA from two types of creatures with no relation to each other at all.

I'd say that the jumping out of a low pressure fireball thing was more of a glaring flaw, but that is one of those where you can't exactly blame them, because it is so universal that people expect it now.

There is sure to be some other reducting element in the atmosphere that the alien metabolism is using and is unsuitable for humans.

It's not an oxygen-poor atmosphere, it's a carbon-dioxide and hydrogen-sulfide rich one.  This book has all the background information and sci-fi handwaving you could possibly ask for in justifying the environments of Pandora.


Also I'm not sure why anybody's having issues with that link to the biologist's article.  It works for me...

Muppet King:
I'm not going to buy a supplemental book for a movie that I didn't really like much.

That would still cause the humans to suffocate and cause the brain to die.  Ten minutes without oxygen and there is basically no saving the brain; after a few minutes there is certain to be brain damage.  Basically, if the humans can't breathe the air on the planet, there isn't enough oxygen to allow the brain to function.

It also still doesn't explain why the Colonel didn't end up a big charred mass when entering an oxygen-rich environment while on fire.  To give you an idea of what it would do, a patient receiving oxygen can severely burn him or herself just by smoking a cigarette; now imagine what a larger open flame would do when immersing oneself in pure oxygen.

LTK:
If I recall correctly, the Colonel did say that in Pandora's atmosphere, you pass out in 20 seconds and die in four minutes. I don't really see why you have a problem with the atmosphere and its chemistry, especially since the indoor atmosphere is not made out of pure oxygen but presumably mimics earth's atmosphere.
