I just finished Book 3 of the "Song of Fire and Ice" series last night. I have issues with the writing style here, but the second half of Book 3 was tremendous. I'm hooked again and ready to continue.
I feel there are too many characters presented, there is too much jumping around across viewpoints, and too much focus on descriptions of meaningless visual details. These books would be better if edited down from 900 pages in my opinion.
With that said, there are many that think this is the best fantasy series by the best writer in the genre, so if you aren't familiar with it you should consider checking it out.
