I'm a late follower of this series having just binge watched the last 7 seasons and now i'm addicted. Sad that this will be the last season of the show, i also read that there will only be 6 episodes albeit each will be longer than the normal 60 mins.
The good news is that they are contemplating a spin off set in the years before GOT
