The ending was badass IMHO. Django is such a frickin badass
I get what you're saying about SLJ. But thats what makes the character so complex. He's this loud buffoon in front of Candie and his friends. Its how he gains power, access and also fools people into thinking he's harmless. Then behind closed doors in the library.....he's the true *villain*. Candie was badass villain as well...but its Stephen who runs the show. Calvin is just the front. I thought it was great writing by QT.
*notice the Cane drop at the very end*
I kinda wish he told a story about being a quickdraw is his younger days (give a short monologue how the master taught him how to use a gun to frighten the slaves years ago or maybe something else) and then a "duel" between him and Django at the end.
But overall...yes its a badass ending.
