James Cameron's Avatar is not a critique on violence
On the surface it appears that Avatar (the one with the blue people, not the Last Airbender) is a critique on imperialist violence, one long overdue in our culture. But the movie falls short not just once but several times, changing from a thoughtful social commentary to just another feel-good, white-savior blockbuster. I'm not here to critique the writing, though god knows it needs it.
I'm here to talk about how Jake, the wounded soldier, still endorses violence as the only option to take down the Colonel. "I was hoping you'd say that?" And then the film's narrative dances around having Jake kill the Bad Guy, because oh my god can't have your hero kill someone on screen. Though apparently Jake's killed lots of people before.
On the surface, the final battle is won (with Eywa's help) to preserve the balance of the land. This is undermined by the blatant glorying in death the film takes – the battle is framed as heart-stopping, glorious, something to revel in when you are winning and to dread when you are not.
In the end, the day is won with more violence, endorsed by a deity. There is no even stopping to think on the harm done after the battle – the casualties are swept under the film's rug, because they died for a good cause right? Oh, and some of the 'good' humans get to stay. Even though there'll be no funding for their equipment to be maintained and it's likely they'll NEVER get back to Earth. Oh well, they can live on a planet with floating rocks and air that's poisonous to them, right?
