I agree with KayB.
considering there were slave uprisings and slaves escaping together, I would assume that there was some friendships being formed. I didn't like that the movie made it seem otherwise. They even made mention in the movie as to why slaves didn't get together and fight
I wasn't suggesting the Django, had to make friends, but could have at least shown some solidarity. something. Anything. If they thought enough to have the slave smile, they could have thought enough to have Django say something.
In my opinion, the single-mindedness of the character made me dislike him. The doc helped him, he could have helped the slaves and it could have been in form of some quick suggestions. heck, they helped him. After the way he treated the slaves at Candyland, they could have lied and made sure he ended up in the mines right along with them.
