I would wait a couple of years, when the twelth and supposedly final book comes out. That way if you do like it, you can read the whole thing up to the ending.
Reading Jordan is like panning for gems. You have to get through a lot of dirt to get to the goodies. He can write individual scenes with the best of them. But he doesn't seem to be able to sustain that quality over the thousands of pages in his series (few writers could sustain such high quality over so many pages, to be honest).
In this case the "dirt" you have to wade through is a lot of descriptive fluff about women's dresses and the contents of rooms (though to be fair, some people love that stuff and think it makes the world building a lot better). There is also a cast of what seems to be thousands of minor characters, who all started running together in my head after awhile, and all have similar names and characteristics.
In a series this long, everyone is sure to find things and characters that they love, and also some that they hate.
If you do decide to try it, read the first couple of books. I thought he didn't really start finding his own voice until the second book - the first one was more of a typical fantasy quest sort of thing, and he starts developing his world better in the second.
And prepare to be frustrated. As I said, Jordan really can write well at times. The Battle of Dumai Wells, seen through the eyes of various characters, was a rich and rewarding read. As good as any fantasy battle out there. But not everything he writes is as compelling. And the pace of the books really slacks off in the later books of the series (though he seems to have gotten things moving along again nicely in book 11).
I think a lot of the people who hate Jordan do so because they are previous fans who got really angry over the slow pace of some of the later books in the series. At least that is the feeling I get from posts at the Martin board where I am a member, and where people like to diss Jordan a great deal of the time.
As with all things in life there is the great, the good, the bad, and the ugly. You will try to try it out to see if your great and good outweigh your bad and ugly.
