SHIELD
This version of Capt. America was worse than the 90's movie version.
The costume was totally wrong. When I see it, I shouldn't have to ask "who are you?", I should be able to recognize who he is.
The biggest problem I had is with the plexiglass shield/fairing on his motorcycle. The shield did its job but when you have sparks from gunfire bouncing off of it-it's not just an insult to mine, but to every viewers intelligence.
I've only seen him 'throw his mighty shield' once and he missed the badguy completely. The shield did return to him but did he catch it? Of course not. It landed at his feet and he stared at it like a dog would stare at a rock if you tossed it at his feet.
Everything that makes Capt. America what he is was not put into this movie at all, only the name.
