I thought Hiddleston was great, though having only seen it once so far, and that a while back, I am not sure how deep my thoughts are right now. I recall being most struck by the Agincourt scenes, which he did very differently than Branagh; I had more a sense that this is where Henry V became Henry V instead of Hal, like he's stepping up in the moment to do the thing that needed to be done. There's also more of Prince Hal in the production than there was in the Branagh, so you get more of a sense of how he's grown and changed. Now I want to watch it again to see if I'm remembering accurately!
