I find it weird that people can 'hate' SoI&F.
There more I research individual characters, like on the wiki
http://awoiaf.westeros.org/index.php/Main_Page, the more interested I get in each storyline.
If you do that, say when it comes to the first book, you notice how some of the conspiracies intertwine. Martin was good in making many look coincidental & pure luck for each conniving schemer. And more broadly, the detail and effort Martin has made for history, characters, etc, is quite breathtaking.
I'm almost halfway through Feast of Crows and now feel a fanatic, because I've researched ahead more than when I read Tolkein or CS Lewis. Martin does have his +s that the average sci-fi writer clearly would just skip or not think of.
