It was nice to see a character arch for Ross but there was definatly no character arch in Sam. I felt like he was the same person at the begining of the film and at the end of the film. They never even said how he got the 2nd suit? Apparently Wakandans sent him 2? I will say I don't buy his ability to take a beating and then just get up and go. He is supposed to be a normal person but he doesn't feel very normal.
