I haven't had the pleasure of playing through all of the story lines just yet, but having experienced that Charr and Norn (the beginning part anyway) storylines I both agree and disagree with you.
No, the story wasn't the most amazing thing I've ever heard, with a fairly predictable direction, but I can understand why Anet developed the story in such a way. With what I understand, the personal storyline is supposed to help direct you towards zones that are level appropriate, not so much as to dominate your gameplay, such as it was in SWTOR. However, having the personal story does give a bit of extra flavor to your character. I choose to view these as racial stories, what I mean is that how each race has special abilites, in your "home zones" you have an extra questline to develop GW2 lore, which is a bit of an upgrade over a system like WoW's, which had the same quests regardless of race/class. (neither of the previous statements were meant as an attack on WoW or SWTOR, just using them as a comparison.)
Ulitmately, it seems that with the system of dynamic events, plethora of exploration options, and the personal choices involved in GW2 dungeons, "your" story in GW2 is almost what you make it. Reading reviews, talking with fellow players, and even sublte hints from the developers seem to leave the understanding that your GW2 story is going to be a derivative of what you put into it, completely seperate from the actual pre-developed storyline.
So while I do agree that the pre-developed story isn't groundbreakingly amazing, it will do its job to keeps players guided, both older players and the younger players looking to get a start in Tyria. I did however, enjoy the simple story present to me by both races (Norn and Charr, I am avoiding the Human until release), Yet, I still disagree that the story WONT be dark of jaw dropping, because if you want it to be that way, you can probably make it so, either through personal choices in the storyline, or involving other gameplay aspects.
