yep.
Seasons 1-4 were the golden times for GoT. GRRM was still aboard and all Dumb&Dumber had to do was retell the books.
Seasons 5-7 was mediocre, as book material ran out by the end of season 4, but they had a good foundation on which to build. It started out promising. The more the show progressed the worse it got.
Season 8 has been a total trainwreck and for anyone to say it's good, just boggles my mind. There's no way anyone can enjoy the writing atm unless they have totally forgotten about past seasons... even past few episodes. The writing is that incoherent, bad, bad, bad. Awful.
