2. Spider-Man
Peter Parker is the heart and soul of Marvel Comics.
And he's about as correct as possible in the MCU. Tom Holland is pitch perfect casting, really making Peter his own while bringing out an attitude unseen in filmic depictions of the character. He's my favorite movie Spider-Man for sure.
And because of the nature of the MCU he can be something no other movie Spider-Man was before: an upstart. He can be a kid among super powerful beings. He can look up to the heroes and try to be a hero. He can be a hero while still being a small scale hero. And that's why Homecoming is such a great film. It's a response to the original Iron Man, and is a movie about trying to be good and doing your best.
And that's the purest sense of Spider-Man one can get. And it's all onscreen with the MCU version.
