Considering that Tarantinos recklessness caused Uma Thurman to get injured on set, she probably still has a legitimate beef with him, and without her I dont see a Part 3 happening even though I do agree once should be made in a decade or two.
Apparently she blames the producers rather than Tarantino.
Not sure why, it sounded like he's the one who convinced her to drive the car when she didn't want to. I'm sure there's much more to the story than I know.
The commercial says that Church isn't for perfect people, I guess that's why I'm an atheist.
