It seems like any 'epic' fantasy will have its walking through quicksand slow parts where you just have to soldier on until you get to the lively parts. I kinda felt that way about the Game of Thrones books, especially the last couple. Interesting characters became dull annoying people that were a chore to read about (Daenerys), some of the boring whiny single dimensional characters just tick me off (Sansa) and the interesting ones never seem to get enough page time. Then again sometimes the characters you start out hating develop into characters you respect or understand.
I don't read much fantasy, but big, popular fantasy series are a go-to for my audiobook listening because they're usually engaging and they take up a lot of time so I don't have to worry about sourcing new listening material every few weeks. GoT 1-5 got me from about March to December 2013. Book one was great. The second and third had their moments, though George Martin's limited range as a writer started to show through pretty badly. Books four and five were miserable: boring, repetitive, endless, light on content, with miserable plot development after miserable plot development (when there was any plot development occurring at all).
As for what I'm currently reading: I'm about 15 months into Harry Potter and the Order of the Phoenix in Chinese. I've improved my reading, vocabulary, and self-expression greatly from reading the books, which I chose because they've got an engaging, easy-to-follow, familiar story that keeps me going when it feels like a slog. They're my foreign language books - I've read the series once before, in German, and there's a good chance if I choose another language in the future I'll be getting a set in that language, even though I've never read them in English.
I'm also a bit past the halfway point in "Imperium" by Ryszard Kapuściński - a Polish journalist from the mid-to-late 20th century who does great literary journalism. This one's about the sprawling, bloated politicomass of the USSR, pre- and post-fall. It's a bit disappointing, the other stuff I've read from him is incredible (and I'm not a non-fic guy), and the social injustices of the USSR are a favorite read (especially Solzhenitsyn), but "Imperium" kind've drags.
Up next, for a sure thing, I'll probably finally crack my copy of "I Am Asher Lev". Chaim Potok is incredible. I need to get a copy of "Bleeding Edge" too, or maybe dig up my copy of "Gravity's Rainbow" again - 2015 needs a little Pynchon.
