I actually really enjoyed his portrayal of John Walker. I thought Wyatt Russel did a really good job of making a character despisiable but also very grounded. I think he kinda of showing what any normal non avenger person would do if they had the serum, they're friend died, they covered up their actions in Afghanistan, etc. I think we were supposed to hate him or like root against him but it was just so well done that u had to respect him.
