Spider-Man pioneered modern superhero movies because it provided a lucrative template that is frequently parroted today. However, despite the copycats, Spider-Man stands out because it lacks the cynicism that has become the norm. There is no sign of cinematic universes. There is little merchandising or fan service. Really, it's just an origin story being told, which is oddly refreshing. It's hardly original, but the fact that it isn't treated as a stepping stone has become rare with superhero movies. Thorough characters, quotable dialogue, and memorable moments are hard to come by these days.
Furthermore, Spider-Man is made with significant craft. Director Sam Raimi elevates the project in a way that is sorely missed today. The cinematography is packed with motion, even during innocuous establishing shots. The editing is equally energetic, using flashy transitions and montages as opportunities to spice things up. The sound design is complex during battles, subtle during emotional beats, and abstract during moments of discovery. Meanwhile, the soundtrack and cast are noticeably excellent (shout out to Danny Elfman, JK Simmons, and Willem Dafoe). All together, this makes Spider-Man a classic film that's often imitated but never replicated.

Wilelm Dafoe is also great in this movie even though the green goblin outfit feels dated. His voice is just great.
Man your first paragraph really nails it on the head about this movie and how other movies try to imitate it. It still feels fresh even after 20 years.
