I think a critique or analysis of the internal consistency of AGoT is valid and fun! The blog is fascinating in its depth. I just don't think it's necessary to call the books or show "shallow" when they deviate from real-world history or plausibility; like the late Terry Pratchett would argue, it's all about "the story". And the story is engrossing, in my opinion.

You'll get no argument from me about the TV show getting inexplicably rushed and inconsistent in the later seasons. I think most viewers were disappointed by that :(
