I picked up one of these books shortly after reading a Terry Brooks book. I, personally, can't stand Terry Brooks books. So, comparatively, Jordan's books are much better.
But regardless, I've enjoyed his series okay. It's not phenomenal, it's not great, but it's okay. It was okay enough for me to read the first 8 books (just haven't gotten around to purchasing the others). Put it this way: I wouldn't buy this in hardcover, but I'll buy the paperback when I can't find something else. It's like an old pair of shoes: they aren't the best looking things in the world, but they're pretty comfortable.
One of my main complaints is how annoying some of his female characters are, and even more so when there is a romantic relationship between main male and female characters.
