Spider-Man 2
This movie actually inspired me to be heroic (Thanks Aunt May!). I read an article about how Stan Lee wrote the original Spiderman comics (which are also awesome) so that Peter Parker was relatable. Many of the superheroes in comics at that time were 'super', but not 'super' relatable to actual people. He wanted him to have real life problems that would resonate with the average person. Well, this movie portrayed that vision beautifully. One of greatest superhero movies of all time.
