Toby Maguire made for a good nerdy Peter Parker.

Andrew Garfield really didn't do it for me, but I think he made a better Spider-Man than he did a Peter Parker.

Tom Holland was actually still a teen when filming Homecoming and he does a good job with the character of both Peter & Spidey. What I didn't like about Homecoming is:
1) Peter looked like he could wipe the floor with Flash Thompson. What the hell?!
2) Spidey relied more on the suit than his actual powers. He became less Spider-Man and more Iron Man Jr.
3) The Vulture learns Spidey's identity. After reading Ultimate Spider-Man I'm so sick and tired of every other villain learning Spidey's identity!
