Rob Dreher is more patient with Avatar than some of the other reviews linked to:
I finally made it to "Avatar" today. Whatever else there is to say about the film, it was well worth seeing for the visual spectacle alone. I saw it in 3D, and it was great fun. It’s also fun, in a way, to see it as a Rohrshach test of one’s political and cultural orientation. "Avatar" has been thoroughly analyzed as a cliched story about white guilt/reverse racism, cheesy noble-savage mythologizing, cheap anti-capitalist fantasizing, pantheism, environmentalism, anti-militarism, and so forth. In its storytelling, "Avatar" is not morally nuanced, or even sophisticated. And yet, I found myself enjoying the film more than I expected to, and I believe that of all the criticism I’ve read of the picture, Conor Friedersdorf’s take seemed the truest to my own experience this afternoon. Here’s a bit of what he had to say:
Ultimately all these critics miss out on a rare chance to reflect on the tragic flaws of earth and humanity in a novel way. Think back to those basic kinds of narrative conflict we learn about in elementary school. Man versus nature stories show us how the hard realities of the human condition impact our lives. Man versus man stories render the fallen nature of our species: since at the Greeks we’ve understood that we’re condemned to be forever hubristic, greedy, violent, jealous, etc. In Avatar, we’re shown a foreign world where creatures and nature are similar enough to our world that we understand them, different enough that they can help us reflect on ourselves and our planet as never before, and rendered so spectacularly that as much as any movie I’ve ever seen, we’re able to conduct this mental exercise by really feeling that the creatures and habitat we’re viewing are authentically there and different. "The audacity of Cameron’s movie is to make believe that the artificial world of computer-generated graphics offers a truer realm of nature than our own." (link)
Sure, I wish the villains would’ve been a bit less one dimensional — Avatar isn’t an inquiry into the characters of individual humans or the nature of evil doers, nor is it a masters class in intricate, delightful plotting — but the characters and the plot serviceably accomplish their main objective: putting us inside an alien society and landscape, awing us with its contours, and threatening its destruction so that we feel how thoroughly we’ve grown to like its best attributes.
The rest here.
