Despite the fact that RW likes it, it's still a great series.
(Kidding, I'm just playin' my man. /forums/images/graemlins/wink.gif )
The first book was a great action/fantasy story that hooked me into it. But the great thing about the series is that as soon as it's in danger of getting boring and repetitive, it changes its focus and keeps fresh. The major shift in direction was in terms of plot, where the enemy changed from the evil Rahls and the "Keeper" to the Jagang's Empire.
But the most surprising and recent shift was hinted at in Soul of the Fire and came to complete fruition in Faith of the Fallen: the series has become an allegory for Ayn Rand-ian Objectivist philosophy. It hit me like a sledgehammer while reading Faith (ironic title, then, eh?). At first I was a little worried, as I hate being preached at. But the story was still good and I was more forgiving since I generally do agree with that world view.
