I loved the books when I was younger, although I haven't read them in a long time. I'll stick with the show until the end, but even my wife (who is generally way more tolerant of TV shit than she should be) is struggling with this show.
I don't blame her. Not much is happening, the characters are mostly idiots, and I don't get any sense of urgency about their quest. Some of the production design is really nice, but everything else seems really sloppy and I'm kind of disappointed even though I went in with few expectations. Maybe I'm just too old, maybe I don't remember as much of the books as I think I do.
