Amazing Spider-Man #82 comic book from Marvel Comics Group
I always liked Electro.  If there was a villain who would do well in a Spider-Man movie, it is him.  Granted, Kraven, the Lizard and Scorpion would be pretty good as well.  Just no Vulture, he is dull as dishwater.  Rhino is pretty dumb too.  Now if you put him in the Hulk movie, you may have something.
