And you make it sound as though that's Phil's one solitary claim to fame. "Oh boy, he decapitated Kingsley!". It was cheap; done to make the new guy seem cool for seemingly taking out the original guy. And that's assuming that's really:
A) Kingsley under that mask.
B) And that he didn't manipulate Phil into believing he had done that with the Winkler device, or what have you. Which would explain the rash behavior exhibited in Phil (it happened to Ned Leeds) and why he never uses his lunatic laugh outside of costume. Perhaps he was manipulated into believing he had been able to keep his laugh without use of that mask. But if that was the case, why does he only use the laugh in costume. Hmm... Those are just a few of the many plot-holes in the "Kingsley is dead, nuff said" debate. You'd best hope it's not revealed Kingsley didn't get decapitated, or else Philgoblin will have NOTHING to his name worth mentioning. I mean, according to you, seemingly chopping Kingsley's head off is all he's got. And it wasn't even conclusive.
And if you don't measure a character by his accomplishments, then how do you judge a character like Phil, hmm? It can't be because he is a likable character, because really, I fail to see anything likable or endearing about him currently. As I and you yourself admitted before, the dark mirror thing's been done, so that's out; it's not 100% unique. What then, in your opinion makes Phil the great goblin you make him out to be? I'm just not seeing it, and I'm trying to, for argument's sake.
And yes, a good deal of the 90's were terrible; I would know, as well, seeing as that was when I was introduced to Spider-Man and his world and started reading the books. But at least we can both agree one ONE thing: Bagley did a good job on art. Though I do fail to see how that pertains to any of this.
