ok honest answers please.

I did watch the show twice over and I thoroughly enjoyed it. I'm not an avid reader of sffg but since I have retaken to reading I have read the first law trilogy and I'm not with the gentlemen bastards, which I am enjoying quite a lot (although Abercrombie has left me amazed)

I did read the hobbit, LoTR, and the silmarillion back in my time, so at least you know where I stand. I enjoy fantasy but I haven't read a lot of it in the last few years.

Will I enjoy reading ASoIaF even though I know the show by heart? is it worth gulping the 8000+ fucking pages of it? what say you
