I highly disagree. I think that Dan has got the essence of Harry spot-on.

As for the Ron and Hermione scene? I don't know, I'd have to see. However, not being a "shipper" in the least (I don't particularly care for either of the romances - I'm more of an action person), I will have to say that I've always thought that strictly from an actorly standpoint - Dan and Emma have much better on-screen chemistry than Rupert and Emma. That's why I think they left in the dance. (also face it - even if you're hooked up with someone else, if you're on the road for weeks at a time alone with one person, not knowing if you're going to live to see the next day, well - in real life, Harry and Hermione would have been comforting each other a bit more)
