Game of Thrones is probably the most disappointing piece of media I have ever experienced and it will be tough for anything to top it. The show started off so strongly and it could have been an absolutely legendary series, and in like two seasons it went from that to me wanting nothing to do with it ever again. And yeah, if (giant if) GRRM finishes the books, I bet they are going to be just as phoned-in as the show, since he obviously has lost his drive to complete them.
