Good but always questions when time travel is used

Rating: 8/10 (31 May 2019)

Paradox's paradox's paradox's. My main question is, if captain America went back in time to be with his woman, what happened to the captain America that was already there in that time? Did future Steve Rogers kill of past Steve Rogers? And if Captain America wasn't around then how could everything in civil war and the winter soldier have happened? Anyway I enjoyed the movie but wasn't anywhere near as good as infinity war.
