It's definitely one of the best movies in the MCU and the best one of the first 2 phases. We get introduced to Falcon for the first time! Also Hydra is Back and they are literally nearly the whole S. H. I. E. L. D team. Nick Fury is quite important aswell. Everything in there feels fresh. It's perfectly written and feels big. S. H. I. E. L. D is destroyed. That gives Agents of SHIELD a nice crossover story as well, where we get more information about the Death of SHIELD. Amazing movie.
