I really enjoyed this series. I had read it all prior to the show, (minus Dance with Dragons which wasn't out until after the show). GRRM does a lot with relatively little, and does very well. There are actually fewer plot points in GoT than my actual favorite series, but he does a good job in making it feel like there's a lot going on all at once.
I didn't like Dance with Dragons AS much as prior books, but that may have been my dissatisfaction with the show shining through.
I loved all the books in the series, and I think I was excited about reading ADWD because during A Feast For Crows I was so curious about what everyone else was doing, and how their stories were going to continue.
I loved Tyrion, but the whole "Where do whores go?" Started to bug me, although, once he was on the boat with young Griff and the others he became one of my favourites again, especially when he was taken a slave.
It's funny how during the series different characters/ stories started to shine, and the favourites list would alter throughout.
Definitely agree! There was a while in the books where Littlefinger was my favorite purely for how well he played the game.
