I wouldnt call the story bad. Its well above average to good so far for me. Compared to most games that have come out in the last several years its a spectacular story. We'll see what the ending does for me. Like I said, I assume it'll be kinda disappointing, being the middle child, but sometimes you have to look at the trilogy as a whole.
Its also got nice enjoyable gameplay. Not over the top hard, but certainly challenging enough to keep you going and easy enough to pick up. Not an addicting play through over and over again game like Diablo 2, but certainly worth more than 1 or 2 play throughs and one of those games you might get the urge to still play every now and then in 5 years, like Knights of the Old Republic.
