I promise you no spoilers in this post unless you think the Cap walked through the whole movie and didn't fight anyone.
It occurred to me about two thirds of the way into the movie that all those bad guys shot at Captain America and their bullets bounced off his amazing shield. Now don't get me wrong, I'm not for bad guys but I wonder why not one of them thought to shoot him in the legs. They were sticking out there the whole time. After ten of your bullets bounced off a shield, wouldn't you rethink your strategy?
I know that would be a boring movie but I'm just sayin'.
