3. Iron Man

It's amazing just how formative Iron Man was.

For a film that built off of decades of super hero films, it also perfected the formula for making them work it's a huge, wonderful, special as all heck movie and introduced us to the classic character people love today.

And Iron Man was maybe at his most hatable at this point in time in the comics. He was a tin plated tyrant responsible for the first Civil War, he was the authoritarian head of SHIELD, he had just been Secretary of Defense for the Bush Administration, it was a bad bad time. But thankfully, Matt Fraction and Salvador Larroca came along to make the comics good and Marvel Studios knocked the film out of the park. But to be honest, without Robert Downey Jr., I don't think we have an MCU.

He was so perfectly cast and just owns every second of screentime in an undeniable way. He's an all-timer for superhero cinema and we're all lucky to have him.
