Well, I've read the books (pity me, no ending) and the series, and I have to admit watching a show where nearly all the characters are just literal pieces of shit to each other isn't for everyone. I won't down vote you, but I enjoyed it, even though I can see the lack of appeal to some.

The first time I read the book I put it down for 2 years because Cersei killed the dog. Noped right the fuck out after that. When I did read it I was was constantly thinking how shitty all these people were and it made me wonder, do many people go around with those kinds of petty vengeful dialogs in their head all the time? Is that actually realistic for so many people to be like that?
