5. Emma Stone's Popularity
While I'm not quite on the Emma Stone bandwagon like everyone else, it's undeniable that she is one of the most popular young actresses working today. The selling point of a Spider-Man film is, of course, always going to be Spider-Man, but it doesn't hurt to have good actors who are well liked in your franchise, and Stone is one of the most loved actors in this new series. Even people who were critical of The Amazing Spider-Man praised her, and the romantic chemistry between her and Andrew Garfield was a highlight of that film. Sony, and the filmmakers, while wanting to stay true to Gwen's fate in the comics, no doubt also want to keep Stone in the franchise as long as they can. She brings goodwill towards the series and is one the stronger love interests we've seen in a superhero film this past decade.
