If they only make Spider-man movies where Peter is a teenager than the character will never grow on screen, and that's just boring. Look at what Nolan's doing with Batman. I want a definitive beginning, middle, and end to Peter's life story (doesn't mean he has to die or anything). Frankly I think it'd be cool to see a Spider-man movie with Peter Parker in his 30s, married, working as a science teacher/professor, and juggling family life with his life as Spider-man.
