You're going to find some varied views on this subject. Personally, I haven't actually finished the series. I have read through book four twice and got to six the first time through. This isn't because it's bad--it's because I was in middle/high school and I really didn't like reading much. If I could get through 6k pages when I hated reading, that's saying something.
I am still going through the series right now, but took a break to read Mistborn and am now reading His Dark Materials before I trump through the rest of WoT. All I can say is, it's worth a read. I know what happens through the rest of the series due to the fact that many of my friends are raging RJ fans. There is a book or two in there in which, like others have said, nothing really happens...but I have a feeling I'm going to enjoy them (and the series as a whole) anyways.
I took a course on LOTR a while back and I asked my professor if they had ever read RJs books, and this professor pretty much exploded claiming that he(RJ) was a horrible author. Then, just the other day, I went to go ask a person from my fiction class if she had read the WoT since I saw some themes in her work that Jordan had in his, and that same professor freaked out and ardently expressed the fact that Jordan was in fact 'a hack.' Now, this specific professor has never read the books...way to go, right?
To be honest, those sort-of opinions should be taken with a grain of salt. The books that I have read so far are excellent, and I have a feeling that the rest (especially The Knife of Dreams) are great pieces of epic fantasy as well. Read them. I highly doubt you'll be disappointed.
