I don't see why people are so up in arms about RDJ in Homecoming: 1. Iron Man + Spidey = $1bil+ box office 2. The MCU has shown that they can have other heroes as supporting characters in the main hero's solo outing and have it make creative sense without compromising/derailing from the star of the movie (e.g Black Widow in TWS, the abundance of heroes in Civil War) 3. People who claim that Spidey never needed other heroes in the comics seem to be forgetting something: comic Spider-Man is the king of team ups. He's had more cross-overs than any other solo hero in Marvel, so of course he was going to have another MCU hero in his solo 4. Given what happens in Civil War, particularly the Stark/Parker bond that is formed, it would be pretty surprising if Stark wouldn't be checking up on the teenage super-hero he discovered (especially given his stance on accountability, he'd want to make sure the kid is keeping in check) 5. People seem to fear Spidey being upstaged by Stark in his first MCU solo outing, but forget that the reviews of Civil War seem to be in consensus that Peter was the scene stealer of the film (which not only had Iron Man, but the main Avengers minus Thor and Hulk, Ant-Man and the incredible Black Panther) Sony and Marvel both know how important this movie is for Spider-Man, trust me they're not going to screw this up
