Here is why I think it's better than Spider-man (2002)
Spider-man is not necessarily bad, but I feel that the S piRaimi origin story had some weaknesses in it, that the reboot avoided. I feel that in the 2002 one, Spider-man is having too much fun with his powers, when he wakes up all muscular and cheering himself on as he jumps from building to building instead of being more scared and confused, like in the 2012 one.
I also do not like how in the 2002 one there is the unnecessarily love triangle going on with Mary Jane, which really doesn't do anything for the movie, since we know she is just going to go for Peter in the end anyway, so what's the point? I also do like Connors better as a villain compared to Green Groblin, but the Green Goblin was not bad though. Just thought Connors was better.
I also like how in the origin story of this one, Peter, after not being able to find the vigilante, follows Captain Stacy's philosophy, about helping people in general, rather than constantly going after one guy, as a crime fighter.
In the 2002, Spider-man catches up to Uncle Ben's killer, and the killer accidentally trips and falls out the window, which felt like a forced convenience from the writers, since they didn't want to have Peter kill him, nor choose to let him live. It just felt like a convenient way to end the subplot.
But those are mainly the reasons why I like the 2012 one better. What do you think?
