Well, I've go to say that Spiderman goes through genuine angst. His father figure died because of his pride. That alone is enough to throw somebody into angst, however it turns out there was absolutely NOTHING he could have done to prevent Uncle Ben's death as it was nothing more than random violence. That made his guilt trip EVEN WORSE because it showed him how absolutely powerless he was over the whole ordeal.
Twilight on the other hand, like everything else it attempts to do can't even get the angst right. Why is the girl angsty? her stepfather plays baseball? She moves from Arizona(?) to Washington(?)? All the guys think she's cute? much like the kids who like Twilight, she has no idea why she's angsty other than to be angsty. Vampire boy? he's kinda understandable. being 17 sucks, and he's perpetually 17. He's been the random angsty 17 year old for the past 200 years or so. I'm certain that after that much time of being angsty, he's just gone a little crazy. Wolf boy well, the girl he likes is in love with another boy. That's just typical highschool, so that's kinda understandable as well.
