The trailer for Django Unchained is finally out:

TNC says the film isn't for him:

It is not merely wrong to focus on the militarism of the Civil War because those who do so generally don't want to talk about slavery. It is wrong because such a focus says that the only thing important about war are those who carry the guns. But any serious investigation into slavery, and its violent end, reveal that to be false. Frederick Douglass standing up to his master and stomping a mud-hole in Covey the slave-breaker is iconic. His wife, Anna Murray-Douglass, risking her own freedom and her own life to facilitate his escape, is not.

Earlier thoughts from TNC here. Alyssa Rosenberg has mixed feelings:

The movie may turn out to be an exploration of how much Django enjoys the work he’s meant to do to earn his freedom, but there’s something uneasy about suggesting that slavery under one set of conditions is unbearable while under another it’s sort of awesome. But Django Unchained might be a more interesting movie if it explores what it means to hold a man hostage against his liberty, and what you’ll do to achieve it.
