I mean it's Game of Thrones for me. I absolutely adore that series of books, and whilst the final 10 episodes of Thrones absolutely sh*t the bed, I still adore the show, worts and all.
Only issue is that I've not read the books in a good 11 years (since the release of Dance), so a lot of my memory of them is bound to be somewhat skewed by what I witnessed in the show. I'm hoping to fix that soon with a re-read over the next year or two.
