I can't really say I've hated any of them, although The Sword of Shannara left me pretty underwhelmed even at 15, and I found On the Beach a bit dry,
and The Book of the New Sun still felt like a chore after 150 pages, so I let it lie. Lots of portentous foreshadowing going on, which was irritating - "I meant this promise at the time, though I have broken it since, as with so many others" - that kinna thing. Howandever, John Clute and Ursula Le Guin among many other heavy-hitters think it's hot stuff, so I may well give it another go at some point. It does have a genuine sense of strangeness, of other-worldness, which most fantasy, ironically, doesn't.
Can't say I've really loved any of them either, except A Wizard of Earthsea and, at the time I first read it (age 12?) and for a couple of years afterwards, The Lord of the Rings. I have quite a few doubts now about many aspects of LotR, both in concept and execution, though the scale of it is still awesome, and its essence, which seems to me to be a fable about hope versus fear, and the pitfalls of pride, is laudable. These things are pretty much lost on a 12 year-old though, for whom it's just a very long, satisfying and totally involving story.
So an asterisk in brackets for it, then, and for Dune. Again, I loved at 15, but recently read a few pages at random and found it pretty long-winded, which made me understand a little better those who, like Harlan Ellison, have made many attempts on it with the best intentions, and have simply found themselves unable to get through it.
The other asterisks indicate either that I would recommend the book, or that I simply enjoyed it. If this seems an unnecessary distinction, I recently finished Eastern Approaches by Fitzroy Maclean, and while I'm glad to have read it, and think it's got a lot of good stuff in it, and would happily encourage other people to give it a go, I didn't actually have that great a time reading it - there's something rather flat about Maclean's writing - weird, when you consider how adventurous his life was between the ages of 25 and 34: Foreign Office, Paris, Moscow, Stalin's show trials, SAS in North Africa and Persia, with the partisans in Yugoslavia, liaising between Churchill and Tito.
A chance for Joe to get his own back, and (rightly) take me to task for not having read Alfred Bester. Of the rest, I would like to have read or attempted the Clarkes (I have Childhood's End somewhere), Sturgeon (ditto), Farmer, Smith and Bradbury.
