George R.R. Martin promises he’s more involved with this Game Of Thrones show
If you can believe it, Martin didn’t really work on those last few seasons

The Game Of Thrones backlash wasn’t born overnight; it was a slow-moving caravan of snow zombies approaching a poorly-lit castle that no one could see on a home entertainment system. The show slowly went off the wheels, starting with season four, going from highs like the “Red Wedding” to lows like an Ed Sheeran cameo that not even Sheeran himself could enjoy. The brutality and unnecessary sexual exploitation began eating away at fan faith long before the Bran the Broken monologue. Something was off, even if fans couldn’t put their fingers on it until it was too late.
So what the hell happened? Well, it turns out that it’s exactly what everyone assumed: George R.R. Martin stopped contributing to the show. As silly as it is to prop one person’s contribution to the series as the reason for its failings, the problems with the show’s final season boil down to writing. Characters untethered to reality were making bizarre choices that the show struggled to justify and retcon (though this writer might be the only Thrones fan that found Hodor’s “hold the door” scene a Shymalanian twist too far).
