They'd make terrible, boring TV.
I'm glad they've not attempted a shot-for-shot remake of the books as a TV show, and instead chosen to adapt by taking some of the core ideas and (thusfar) general gist of of the stories and turn them into something. I'm glad I get to explore those ideas further and put my head in that world a bit more. I like that they've added some other interesting ideas to play with.
I think the moaning is just the same general thing that comes up any time anything is adapted to screen. There's a huge contingent of people that, for some reason, seem to treat the source material as some holy text that's never to be changed instead of just being happy that some of the good and interesting elements are being carried over into a new story.
