So Quentin's go-to recipe when he's out of ideas...
...is to just take a piece of history that went a certain way, and make it go a different way, with some added fourth-wall breaking worldly revenge. IB, Django, and this. It reeks of laziness. It was already done much better and brought to its peak in Inglourious Basterds for instance, and I didn't need to see it again.
"Jews get revenge on Hitler! Black people get revenge on white people! And everybody (especially Hollywood cronies though) get revenge on the Manson family!"
How about a new unique idea?
