And give your own opinions on books you've read too

I want to read some more fantasy novels but I'm uncertain of some of them because of their mixed reviews.

The ones I've read of, and which I'm uncertain of, are:

Terry Brooks, Sword of Shanarra trilogy (online reviews say it borders on plagiarising the Lord of the Rings)

Terry Goodkind (said to be somewhat simplistic and to have a bad writing style)

Ian Irvine, The View from the Mirror Quartet (said not to make sense in some places and for the characters to behave unpredictably)

Tad Williams, Memory, Thorn & Sorrow

Lloyd Alexander, The Pyrdain Chronicles

Guy Gavriel Kay

Julian May, Boreal Moon Trilogy

Mervyn Peake, Gormenghast Trilogy

I already own the following books:

Trudi Canavan - The Black Magician Trilogy
Susan Cooper - The Dark is Rising Sequence
William Corlett - The Magician's House Quartet
David Eddings - The Belgariad, The Mallorean, The Elenium, The Tamuli, Belgarath the Sorceror, Polgara the Sorceress, The Dreamers
Alan Garner - The Weirdstone of Brisingamen, The Moon of Gomrath, Elidor
Robin Hobb - The Farseer Trilogy
Mary Hoffman - Stravaganza trilogy
Robin Jarvis - Whitby Witches series, The Wyrd Museum series
Katherine Kerr - Deverry series
Ursula leGuin - the Earthsea Quartet
C.S. Lewis - Chronicles of Narnia
George R.R. Martin - A Song of Ice & Fire
Jenny Nimmo - The Snow Spider Trilogy
Philip Pullman - His Dark Materials
Katherine Roberts - The Echorium Sequence
J.K. Rowling - Harry Potter series
J.R.R. Tolkien - The Lord of The Rings, The Silmarillion, The Hobbit, Unfinished Tales

It would be good if anyone would like to discuss them or if you want to know more about any of them

Primarily I like fantasy but not really science fiction... I have been recommended books such as C.S. Lewis' Perelandra series and Marion Zimmer Bradley's Darkover series but they don't really appeal to me...
