I think most people agree with you, but my husband and I both loved the episode. If Martin ever finishes the books, it might not be Arya, but I loved that moment. When she started running, I was like, “Oh my god, is she going to the Godswood?” and then I managed to forget about it long enough to simultaneously be as shocked as the Night King and to say, “Called it!”
It wasn’t perfect, of course, but I really liked it (Lyanna Mormont’s death was definitely memorable!) and I’m very interested to see how many people are still alive and what’s to come.
