NJO was one of the best series ever written
It's all about story story story
An extra galactic race comes in, after many thousands of years of watching and probing (yes, KOTOR had them, Mace Windu foresaw them, and Sidius knew they were coming, you could say the whole Palpatine/empire thing was to prepare for the invasion), they come in and kick the crap out of everything they come across until the final endgame. And then the story builds up to jacen Solo's demise.
So much win in those books. But then again, it doesnt have Starkiller or 1337 lightning so the kiddies think its dumb.
