“Let them fight.”
Almost wish they kept Spidey out of the trailers, but that’s a pretty good entrance in all fairness. Also, the rest of the trailer looks epic. It’s got the gritty Winter Soldier feel, and the fights look like they are going to be great. I don’t think it’s a bold prediction to say that the Russo brothers crushed Winter Soldier, is probably crushing Civil War, and will crush Infinity War.
