Spider-Man 2 is a phenomenal follow-up from the first film. Everything from the first Spider-Man is either improved or retained its quality. Acting, action, story, special effects, everything is better.
Tobey Maguire is a better Spider-Man/Peter Parker having to struggle with two lives. Alfred Molina was brilliant as Doctor Octopus. He plays a man motivated by ambition, even when things go wrong and was manipulated by his mechanical arms. I also really like the jokes he makes throughout the film, especially the one about the rubber band. James Franco is more developed as Harry Osbourne with his character being motivated to get revenge against Spider-Man. Kirsten Dunst is better as well. JK Simmons, once again, was delightfully funny as Jameson. Rosemary Harris is also great, returning as Aunt May, carrying the same emotional drama as before.
Spider-Man 2 has more gravitas between characters while enhancing the performances of most of the cast. The film deals with the themes of identity crisis and responsibility very well, especially when Peter Parker loses his powers and chooses to live his life as a normal person.
The special effects in this installment are outstanding. I love how this film pays homage to the Evil Dead movies with the scene where the mechanical arms becomes sentient and start killing the surgeons. Like the camera work and how it looked was unsettling, especially when there was no music playing. That whole scene looked like it came straight from a horror movie, and it was awesome.
The cinematography really is top-tier, thanks to the Spydercam, made specially for these films. This really made the action scenes more enthralling to watch.
The fight scenes in this installment were way better. They are longer, more exciting-looking and the special effects make it look more appealing.
Spider-Man 2 is a masterpiece among superhero film, and my favourite Spider-Man film, period. This installment stands the test of time as being one of the greatest sequels out there, even after 20 years. However, avoid the 2.1 extended version because I feels like it drags the film somewhat.
