The only issue I have with this season or I guess just the plot in general, and it isn't a huge deal, but it's Bran's whole angle. They basically have to gimp his powers or pretend like he doesn't exist for a bit, otherwise he could tell everyone what is going on. He could tell Arya what Littlefinger is planning, he could tell Jon and Dany what Cersei is planning. He could tell everyone what the Night King is planning.
He basically sits there all day and does nothing but have visions and he's done nothing this season sans for tell a couple things to Arya and Sansa, and then tell Jon that the Night King is headed to East Watch.
It's a tad weird following the story knowing the whole time Bran could easily reveal all, but he isn't. Again, not a huge deal, but it is something I think about now and again.
