characters in Marvel have never been chiseled in stone - they are CONSTANTLY evolving
and i'm not sure if you realize but moving pictures are a different medium than still images - audio is different than thought bubbles
I get that women and people of color scare you, but it's ok. it will be ok
What's interesting to me, and what Marvel does really well, is bringing otherwise relatively unknown (unless you're a comics fan) characters to life and making them integral to the MCU epic. I mean, few people outside of the comics world knew who Iron Man, Black Widow and Hawkeye, among many others, were before the MCU movies started. Same can be said for the villains as well.
