Spidey isn't supposed to be the cool in-crowd, type personae... He is supposed to be geeky outsider, who finds himself a reluctant hero through his own misjudgements.
1 we actually see what happened to Peter’s parents
2 I feel like they captured the Lizard and that he felt like a guy that got his mind twisted instead of just becoming evil, I gotta say, I have no idea what it’s like to lose an arm but I’m sure it’s a hard life to live so I can see why it was a big deal for him.
Same with all of the movies: the special effects. I like how they showed his movement: his agility, swinging ability, and web shooting. There's a scene where ASM is webbing up Lizard and crawling on and around him while doing so. He moved just like a real spider and it looked very cool.
