I don't think Avatar is hard SF, any more than- actually, this is a pretty close example; Babylon 5 was. There may be hard- SF elements in an overall mix, but the totality tends towards mysticism and plot for plot's sake, allegory and parable.
This is totally fair. I do think that the Earth-technology was relatively hard, so your Babylon 5 analogy is actually excellent (Earth was hard-ish in a universe full of magic gravity molesters).
(aside; how the hell could they do that and not understand what it was they were producing, not notice that Na'Vi brains had an access port?)
Who said they didn't? Grace knows before the film even starts what's going on, she only has to explain it to the executive and the colonel.
The line is "Don't play with it, you'll go blind" not "Careful, we don't know what the fuck that even does." Also, a scene excised from the script has Gung-Ho Grunt Man "castrate" Arrogant Tribal Leader Guy by maliciously chopping off his braid, so if we take that scene as a guide then even the fuckwit soldiers know how significant that thing is.
but the politics of it were just laid on with a shovel.
There's a very, very good reason for that.
This film is made for a mass audience, and it has succeeded very well in this respect. The mass audience in America has a very cavalier attitude about fucking other countries in the ass and taking their shit, as the Iraq misadventure aptly showed the world. Yes, a cabal of military and industrial interests manipulated the media and hoodwinked lots of folks, but if a larger minority of said folks had stronger moral qualms with killing Arabs then it's unlikely the war would have received such support, or perhaps even happened. Then you have America's destructively manipulative foreign policy in Latin America (which
Avatar alludes to in one line) which is, naturally, downplayed in the media and in history, and most Americans aren't motivated enough to find out about on their own (I don't excuse myself from this either, I don't know nearly enough about recent history as I should, just enough to be rather ashamed of my own country's belligerent arrogance. We pretty much barreled into Grenada and Panama and started shooting people).
Meanwhile, the mass audience outside America has to put up with American arrogance all the time, rather than indirectly benefiting from it. Obviously, the movie speaks to these people as well. Shroomy is quite right to snap back at American armchair genocidists who appear to have missed the point of the movie as badly as the wackjobs who argue that Alderaan deserved to be blown away in Star Wars.
Of course the political message of the movie is not subtle. It's a bombastic space opera war epic. Being unsubtle means it might actually get someone to think about something. Better movies with subtle and nuanced political messages will be intentionally avoided by that very mass audience. Fuck, I haven't even seen
The Hurt Locker yet.
Avatar is not the greatest movie out there by a fucking long shot (see my original, largely critical review) but it does succeed at going what a science fiction story should: reframe a contemporary situation so that people can see and judge it relatively free of their existing political biases. The story is analogous in almost equal measure to the saga of massacre and forced relocation of American Indians and to America's consumption-driven foreign policy today. I hate to invoke TVTropes but I can't say it any better than they do: Some Anvils Need To Be Dropped.
And really, I'm having a hard time trying to grasp what your position actually is. "We're Screwed"?
There's an excellent possibility that we are screwed. I have to hope that we're not.
I didn't mean to pick on you per se, but I'm very upset by the idea that I see around here (not picking on any one person) that we can technomify our way out of the extremely complex chain of events that we are setting off in the biosphere. It bespeaks not only ignorance, but ignorance of how ignorant we are. It is an entirely plausible scenario that in the 22nd century our world could be plausibly described, by a grunt in the throes of hyperbole, as "dead." It will not be completely dead, but we are in the middle of a biodiversity crash that can only be compared to the Permian and Cretaceous extinctions. Even if we take the (horrifying, to my point of view) position that all species that do not contribute directly to human wellness are irrelevant, we are still wreaking havoc on
our own ecology in ways that we have historically failed to predict. Fisheries turn into dead zones, the poor starve in Africa, new chemicals turn up in our drinking water, and success stories (like curbing CFC) are a lot rarer than failures even in "developed" nations. How well do you think the world is going to deal with climate refugees? There's going to be a fuckload of them in the early 22nd century no matter WHAT we do now. I was just reading about an archipelago that's disappearing off Alaska and the president is having a hard time finding new homes abroad for his piddly 100K citizens.
When people handwave these problems with something like "the Singularity will find us cheap energy" it makes my blood boil as surely as if you'd invoked the Rapture.
Eco- pessimism, revulsion against technology- yes, it's out there. How well does it square with the existence of starships?
In the setting? Excellently, if the government/megacorp built a big laser satellite instead of a couple dozen water treatment plants. In fact, there's a good chance I'd be furious if the starship fleet of the Earth was under the control of the interstellar equivalent of Blackwater.
