It's only a poor story if you compare it TO the books. Just STOP doing that. Adaptation does not equal = exactly like the book. The characters are NOT the book characters and never were going to be. They didn't make this series just to cater to the book fans who cling to every detail. Just because they change something doesn't mean they don't understand the book characters. Maybe they simply didn't want to go that way on screen. Maybe they thought show watchers would like it better. Who knows? In fact I just skimmed over that post because I knew exactly what it would be and I couldn't care less.
If you're going to keep watching it, just erase all your knowledge of the books at 8:59pm every Sunday and enjoy it for what it is. The books are and will always be there in their original glory for all to enjoy and to bring to life in your own imagination. Trust me, doing so and stopping the overanalyzation helps immensely. Both with your enjoyment of a great show and in not annoying everyone else with incessant book purist bitching.
There are liberties, both good and bad, taken with every single written work that has been adapted to stage or screen. This is just how it is. The sooner everyone accepts that and stops comparing movie/TV Show to book/comic, the better off we'll all be.
