the thing about killmonger's father is that he didn't betray wakanda for personal gain, he did it to spark a revolution after living in the ghetto and seeing what was happening to black people while wakanda was doing nothing.
A lot of these seem like nitpicks that could apply to most other superhero movies, but yeah, I agree with some (especially with the whole vibranium is overpowered stuff)
They mostly are nitpicks. I had a great time and really enjoyed the film. It's probably in my top five superhero films of all time. Almost cried a couple of times because it stirred up emotions in me that I can't even explain.
