Query: I can't believe this is from Martin

I greatly enjoy the first few books in the series and was greatly surprised when I read this one. It seems Martin was too daring and bold with his killing off of main characters in the previous books in the series. Now what we are left with are mostly uninteresting characters and some of the characters that we have come to love have changed enough that they seem like a different person altogether. Killing off interesting main characters is not the problem it's when an author chooses to clean house and gets rid of MOST of the characters that actually made the stories so great is really the problem. We could loss one or two good characters but Martin killed so many of them. This book really does feel like a different book entirely from the series. I'm hoping the next book will introduce some new and more interesting characters.
