I have a bunch of thoughts, though I have to say... James Cameron is a horrible writer. The dialog was atrocious. And everything else you've heard? That it's gorgeous? True. That it's the story of white manifest destiny transposed onto a human/alien conflict in which a white guy/human not only becomes an Indian/alien, but ends up being a better Indian/alien than has ever been EVAR? Also true. Very, very true.
Sigourney Weaver's character was the best Nice White Lady ever.
For those white folks sitting around in denial that this was just a "space fantasy" (written for white people, I assume) and totally NOT about race (and racism) as we know and have known it and that anyone analogizing the Na'vi and name-your-indigenous population is just seeing things.... Well, denial's not just a river in Egypt.
Well, if nothing else that's been written about this film drives the point home, I found the casting... interesting. Here are the actors cast in the four major Na'vi roles:
Zoe Saldana as Neytiri
Laz Alonso as Tsu Tey
Wes Studi (who appeared in both Dances With Wolves and The Last of the Mohicans) as Eytukan
CCH Pounder as Mo'at
But I'm sure that's all just coincidence.
Anyway, other people said stuff about the film that I thought was interesting:
Annalee Newitz: When Will White People Stop Makng Movies Like Avatar?
SEK: Intentions be damned, Avatar is racist (as is praying for and/or to "JaMarcus Manning")
Nick Mamatas, our very own nihilistic_kid: ... Wouldn't it be better if aliens just came down and killed us all?
