Maybe I'm looking into this too deeply, maybe I'm going to get attacked by the '#dylan4spidey'-ers now, but at the end of the day, I think we'll be seeing someone in their late teens, that maybe a lot of us don't know, as our new Spider-Man.
And hell, there's nothing wrong with that. The new faces of the Star Wars saga are Daisy Ridley and John Boyega. Daisy Ridley was only in some unknown short films and an episode of Casualty before this, and now she's going to be the main character of the biggest movie franchise of all-time. Boyega was only in a few small-budget films and wasn't very known either, but he's going to be a household name this time next year. At the end of the day, I think we should stay patient and put our confidence in who these movie studios cast. Look at Ben Affleck as Batman. Opinion on Batfleck has turned 180 degrees since the casting was first announced.
