Read Gardens of the Moon by Steven Erikson. It's very un-cliche, has a complex plot, more realistic characters than the usual good guy bad guy stuff. It's hard to get into, and many are discouraged. I would advise you to stick with it. Then read the next one, Deadhouse gates, and possibly Memories of ice after that. Many people quit at the first book, which is a shame. If you read either Deadhouse Gates or memories of Ice and still aren't really interested, then don't bother with the rest of the series.
Perdido street station by Mieville is good, if you liked The Scar. Though he does have trouble with endings.
Also go for The Lies of Locke Lamorra by Scott Lynch.
The Prince of Nothing series by R Scott Bakker(starts with the Darkness that comes before) is good aswell, though opinion is generally very divided on him.
Name of the Wind is good.
Almost anything by Guy Gavriel Kay is good. Tigana is a pretty strong stand alone, though many seem to count it among his weaker works.
A lot of people complain that Wheel of Time and Sword of Truth series go downhill. Sword of Truth gets criticism for a lack of overarching structure, lack of believeability, and being repetitive, though I haven't read it personally. I've read wheel of time, it's pretty decent. The world has a lot of depth and history, but it is very cliched, and i'm not quite sure that it needs to be as long as it is considering the basic story. Most people complain that books 7-11 ish are really slow, and I'd agree with this. Also be warned that you may find it very cliched.
If you're looking for something shorter, and more straight up adventure fantasy, David Gemmel is a good read. Probably starting with Legend there. On a sort of similar vein, Glen Cooks black company books are good, short, fantasy books. They're not hugely complex, but certainly enjoyable, with some great characters.
