I agree, 3 hours went by quick because the story was just so good, and the characters were so interesting. Still, Pulp Fiction remains my most favorite Tarantino flick. But after seeing Django a second time, I'd say it's a damn close second.
Samuel L. Jackson's character totally reminded me of Uncle Ruckus from the Boondocks cartoon lol. I'm willing to bet Tarantino has probably seen at least a couple of episodes of Boondocks...
My favorite exchange between Django and Jackson-
"I count six shots, n----"
"I count two guns, n----"
LOL. The way he talked at the end reminded me a lot of Dave Chappelle's Rick James impression.
