Comparing Amazing to the Sam Raimi version structurally, implying one is better than the other, is foolish. They're
exactly the same. Replace Goblin with the Lizard, Jameson with Gwen's father, and you're there. They even share the "hero's mentor is actually the villain" plot-point.
You should probably have clarified this line, because it is easy to misread.
First superhero movie that ever did a hero's origin in detail? It's not even the first
Sam Raimi superhero movie with a full origin story and a solid plot. That would be
Darkman (and quite the good movie). There are a number of other movies from around that time which do the same. Superman in '78, Supergirl, Rocketeer, Swamp Thing, The Phantom (goofy, bleh movie), etc.
