This, for me, was what Star Wars must have been for previous generations. The awe and emotion in the final scene, from Cap about to sacrifice himself against Thanos' army for next to nothing, to all of the heroes returning to grand, stirring music, to that final, emotional "I am Iron Man", was just perfect. It wrapped up the Infinity Saga seamlessly while leaving a handful of threads for future films to follow. I couldn't have asked for a better movie to cement the legacy of Stan Lee and Marvel as a whole.
