It is quite obvious when you read, as I do, forums dedicated to both show-only people and book-show people. Show people are constantly amazed, and wondering what comes next, book people are pretty consistently pissed, especially when it comes to Stannis. Why? People have their pet favorites and don't like when anything changes, and can never view these changes objectively for the show's canon. Unless it blows the damn doors off (Hardhome), everything is "bad writing" or "poor logic", when what they really mean is "It isn't like this in the books/my headcanon!"
These threads prove it pretty much every time. It's just bitterness.
