Well, it is great. But the problem is coming. Next week ends the first season which will match the end of the first book. The fifth of seven planned books is coming out next month. It took over five years for Martin to finish it. So even if he finished the final volume will HBO find it's worth the money to try and produce seven seasons of the show? Will the books be finished by the time they are ready to shoot the final series? Can they keep the cast together (minus of course the surprise deaths)? This has been a great effort, but can it be sustained to give us an ending?
