This was a great addition to the MCU. Captain America was his usual self. Black widow was great also and under used. Winter Soldier was a very cool villain. I do wish they did more of his back story. All you got were bits and pieces of it. Falcon was ok. He just found those wings and all of a sudden became proficient with them? The CGI was too notch.

The plot lost me a little. They did not explain Hydras involvement much. Maybe more in a future movie? Or do I need to watch the TV shows?

Also, no spoilers, but the whole reason the hellcarriers were there. I know what they were built for but why?

Just a lot of unexplained questions and briefly touched on answers.
