I have yet to see it, really anxious though. I was shocked to see how much criticism Tarantino took over the "N word" and racial related stuff. I mean seriously, it's a movie set in the time of slavery.
He did a great hour long interview on Howard Stern before Xmas. I'm sure it's on you tube if interested.
Found it. Here's the link, Tarantino comes in at about the 3:00 mark.
