I wouldn't call it interesting, I'd call it uninspired. You want it to be interesting? Have him actually do stuff. Then he can pawn off the stuff he doesn't have time for on you. Make him an actual participant in the world.
Martin: "I'm going to this cave to retrieve the ancient relics of my ancestors. While I'm gone, I need you to go to these zombie infested fields, grab some 'magical' beans, roast them, grind them, and brew me a cup for when I get back. One lump, non-dairy cream."
I don't mean quite like that, but at least make it look like the supposed chosen one is unique in the world. As it stood, they could have just as easily made it my character that turned out to be a Septim. Actually that would have been easier! Then I wouldn't have had that crappy escort quest at the end.
