Err, if you have no clue about what the complains are, then it is better to keep quiet. Have you read the books? From your comments it looks like you have not
No one is talking about continuity errors or plot points ta this moment. Season 5 has completely deviated from the books. A similar analogy would be if in God Father instead of Michael Corleone going back and taking charge of the 5 families, decided to stay back in Sicily and have his empire there. Or in Harry Potter the movies showed Ron never coming back to Harry and joining the death-eaters. That is how much some characters have deviated from the book, taking on the role of completely different characters or different stories to the point that now it follows the book just in name
In some things, if you are not aware what people are complaining about, it is better not to comment. Worst fandom indeed when you are clueless even what is being discussed. If a Harry Potter movie or a Twilight had so much deviations, their directors would have been stoned.
