Interesting that you should mention character growth, Scrills. It had me likening Django to The Bride in Kill Bill. I would say that the Bride grew as a character, maybe because she found out that she was a mother. Django had tunnel vision and it came out perfectly with how he handled meeting up with the Brittle Brothers.

I'm thinking maybe because it's a revenge movie that it become the single driving force, but even then, Oldboy is a revenge movie and O Dasu grew as a character. I'm not sure I like how Django was written even though he is the central character.
I ain't thirsty. There's plenty of fish in the sea, but I don't want all of them, can I have some standards? Or do we just have to settle, for someone's who meh and will do.
