No, I understand that. And all the slaves as portrayed in the film weren’t exactly on the brink of rebellion either - when Django goes all kick-ass on the three slavers, it’s not as if he starts a riot among the slaves to overthrow whitey.
It’s a movie and it has to show the subjugation by means which are visually striking, so it is limited in what it can convey, true.
On the other hand, there weren’t as many slave rebellions as one would imagine would happen in 200+ years: here is Wiki’s list of North American slave rebellions:
1526 San Miguel de Gualdape (Sapelo Island, Georgia, Victorious)
c. 1570 Gaspar Yanga’s Revolt (Veracruz, Victorious)
1712 New York Slave Revolt (New York City, Suppressed)
1733 St. John Slave Revolt (Saint John, Suppressed)
1739 Stono Rebellion (South Carolina, Suppressed)
1741 New York Conspiracy (New York City, Suppressed)
1760 Tacky’s War (Jamaica, Suppressed)
1767 Battle of the Lord Ligonier (Atlantic Ocean, Suppressed)
1791–1804 Haitian Revolution (Saint-Domingue, Victorious)

Not every slave was docile, but not many of them were rebellious, either. Being chronically malnourished and overworked, having been owned your entire life, and living smack dab in the middle of “nowhere to run, nowhere to hide” takes a lot out of people.
Regardless, this is a hijack. Back to the movie discussion…
