Personally I am not so sure, everyone is entitled to their opinion but for some reason it would seem you are actively looking for reasons to hate the series, I mean you seem awfully quick to point out minor impracticalities of the series despite not knowing the reasons behind them while at the same time giving the Dragon Age series a free pass despite being a far worse offender. You may not like the series but the mere fact that it has had such an emotional impact on you to the point that you are looking for the pettiest of reasons to justify your hatred for it only speaks as a testament to how well the series is written, I mean a lot of people really hated Joffrey too but that was because of how well he was written and acted that he invoked such strong feelings in the viewers and readers.
No reason for me to 'actively look for reasons to hate it'. I've read the books, did not like them and didn't think they were well done. Watched the show. Same feelings as when I read the books. End of story.
You are either reading far more into this than there is or looking for an argument so you can say how great(in your opinion) it is. Either way, you should stop now.
