I see your point but what annoys me is that EVERYONE tries to make the stories deep and meaningful and tries to push push the boundaries and barely anyone makes hacks that are like normal pokemon games anymore and that pisses me off... I think that the idea of a deep storyline on a GBA Pokemon ROM hack is pathetic and over rated...
I don't think the idea of a deep storyline is pathetic and overrated, as you say. I think it's more like... everyone's doing it wrong. The ideal "Nintendo" storyline is already laid out and perfect or whatever for everyone that plans to go that way, but there's no real guidelines for someone trying to branch off in a different story direction. I'm definitely sure that it's possible to pull off a deep storyline or whatever, but everyone who has tried thus far has done it wrong.
As far as actually answering the topic, uh, I'm neutral on graphics. Good graphics are nice, bad graphics are bad... whatever. To be honest, though, bad graphics kill a hack more than good graphics enhance one, so if you're unsure about it, stick with the old Nintendo tiles. They're suitable enough.
I dunno if mapping was in one of your categories but my opinion on that is this; if it's not playable, it's not good. "Not playable" can mean anything from 1-tile-walkways to 23-tile-walkways. Edits to already in-game maps tend to fall under "not good" as well, and using your own tiles incorrectly with tile errors tends to make me think poorly of your hack. Just use the stuff properly and I'm good.
I think what Equin said on scripting captures my opinion pretty well; it's the representation of your effort, really.
Originality? What's original nowadays?
I figure my opinion on stories is evident based on my response to that quote up there.
Music, in my opinion, can make a hack. Having the perfect music for your scene can push that level of identification that the player has with the game to a whole new level. It's hard to get the feelings moved when you've got "Viridian City" playing in the background. As far as hacking goes, I'm all for getting the player deep into the game to the point that they feel for characters when good or bad things happen to them, and music really enhances that aspect. I suppose that's why I don't favor "Nintendo-style" hacks where the character just kind of goes around and gets the badges for no particular reason (whether it's specified or not, the player doesn't really care why they're getting the badges). Having player-character interaction is really my ultimate goal when I'm hacking and I think that Nintendo-storyline hacks are not the way to go to achieve that.
