Dances with Wolves: More Than Just a 'White Savior' Movie?

Okay, so we watched Dances with Wolves last night... wow, what a movie. I know it's kinda problematic now with the whole 'white savior' trope, and I get that. But I was thinking about it, and I wonder if it's entirely fair to just write it off like that. Hear me out! Specifically, the scene where Dunbar ends up adopting the Lakota ways, like learning their language? Sure, it's kinda romanticized, but it also felt like he genuinely tried to understand them and integrate. Not just swoop in and "fix" things. Plus, they save him repeatedly too, and he chooses to stand with them in the end knowing what's coming. Maybe the movie is more about Dunbar finding himself and realizing that 'civilization' isn't always what its cracked up to be, and that he was searching for a home and purpose the whole time. If that's the case, maybe, just maybe the Lakota were his 'savior' in a way? I also wonder what it all means that he was trying to kill himself in the first place. I'm still thinking about the question of 'why' someone who is so suicidal would later be willing to give his life for the tribe that he'd come to see as his family and maybe his purpose. What do you guys think? Am I giving it too much credit? Or is there more to the story than just a white guy becoming besties with Native Americans?
