Didn't tear up per se, but they are extremely well executed movies. The characters mostly have a distinct character arc (except for Captain Marvel), and their actions follow their character development. Weaving so many movies and so many characters together into a cohesive story line is an impressive feat. Some of the choices seem obvious now, but were really risky. Like a sci-fi movie featuring a talking racoon and a walking tree. (Closest I got to a tearing-up moment was when Starlord's mom gives him the mix tape.)

Ending Infinity War with Thanos triumphant rivals "Luke I am your father" as the emotional twist to a major blockbuster movie. (Even knowing from the comics what was going to happen, it was still a weird emotional state walking out of the theater after that.)

I think the reason the success of the Marvel movies was so universal was because even people not normally interested in comic book stories still recognized they are executed so well.
