I haven't read the books, but I watch the HBO series pretty religiously. Season 4 has been pretty good, but I still feel it's in the warm-up phase. Nothing really too jaw-dropping has happened, but there's been enough stuff going on to definitely keep the interest high.

Also, House Targaren all the way. Because, well... dragons. That, and Daenerys Targaren is awesome, although it's hard to see her trying to do the right thing only to have it often backfire on her. That's tough.
