Assuming spoilers are cool at this point.
The script is certainly weaker, although not so weak the show is bad. The bigger issue is the show moving all of its pieces in place requires a lot of magical hand-waving. The plot to get Daenerys' dragon up north to die was hopelessly contrived. Everything is so epic and expensive they don't have time to slow the pace down and let the stories breathe.
But the characters remain great, the dialogue is well-written, and the big plot moves are still great because they're built on a really solid foundation. Littlefinger's death made sense (and shocked the hell out of me), as did Jaime leaving Cersei. Danaerys getting with Jon seemed inevitable, even though it feels unearned - another problem of the short seasons.
