As for the Raven's body language in Winterfell, it didn't strike me as different from the one he had in other visions. He always looked aloof and passive, as an observer and that's all.
The Raven said that Bran was not ready to take his place, not that he wasn't ready to influence the past, or to understand what influence he could have. And again, how did Bran influence the past? Hodor was already Hodor. Nothing has changed. The past remained the same, the present too, despite Bran's action. The ink is dry.
We'll have to wait and see who is right. However, it does look like the show (and maybe the book) follows the idea that the Universe is predestined. That kind of temporal loop (Wylis turning to Hodor because of Bran's action in the future) is only possible if there is predestination. As is prophecy. We'll see.
