"Tarantino’s increasingly sophisticated idea and filmmaking are also easily reduced by the minds of some moviegoers. I really like “Django Unchained,” but I didn’t like watching it amid the moronic laughter of some of his movie-geek fans. That’s the fascinating danger of Tarantino’s revisionism. There’s more than one way to love it.

...

Schultz tells Django, “I’ve never given anyone their freedom before and now that I have I feel responsible for you.” But Tarantino knows the history of race in the movies well enough to understand how nauseating a sentiment that is. Django takes care of himself."
