Spider-man is fundamentally a youthful character compared to the others. He provides a nice contrast to everyone else.
It was great that they finally signed on someone who was close to the age of the character. Tobey Maguire was 27 when his first Spider-man film was released, while Andrew Garfield was 29!
In contrast, Tom Holland was only 20 when he made his debut in Civil War.
To put it into perspective, there is only a 10 year age difference between Tobey Maguire and the current Aunt May. He could reasonably play Uncle Ben now.
