Well, I didn't really finish Shannara (vaguely remember them entering a building or something early on in the story), but if you liked that then you definitely want to check out The Lord of the Rings, which Shannara (at least the first book) took a LOT from. Myself, I am not really a LotR fan either. Also, The Eye of the World was dark??? >_> Anyway, from what I know of Shannara, you should like these books.
The Wheel of Time series. ^_^ The first book doesn't really give you an idea of the story to come. Look at it as one long prologue with too much of a LotR influence. The 3 books that follow are really excellent, each one better than the last. After Shadow Rising, a lot of people say that the books fall in quality. They are 100% correct. Personally, I love the developments that happen with book 5 and afterwards even more than the previous 4, but so many chapters (most of them in fact) are just filler with no importance to the main plot. In book 10 CoT, absolutely nothing of importance happens.
So why read them if RJ apparently forgot what the plot was (Tarmon Gaidon) after SR? Thats for you to decide. All I know is that I and many other fans are simply addicted. Oh, and Tarmon Gaidon is coming ^_^-
TGS prologue synopsis

I got chills when I first read that, and it was just a synopsis with absolutely no spoilers.
Other books I love-
The Name of the Wind by Patrick Rothfuss. About myth and legend and a Wizard? in hiding?. I can't do it justice. Read and see if you like it. Can't wait for the second book coming out this year.
Codex Alera series by Jim Butcher. Still reading the first book, and already addicted. Also check out Jim's Dresden series.
