Daniel + Emma caused chemistry issues. Rupert balances things out.
I just re-read the first half of Deathly Hallows then watched the re-watched Deathly Hallows Part 1. I couldn't help but think that the Harry-Ron-Hermione friendship had chemistry issues in the films. In my opinion, here's why:
Daniel overcommits as Harry when in the book he's a bit more modest, subdued and introspective. He's almost a silent protagonist at times taking in everything around him and making the bold moves. Daniel should have taken it down a notch in his performance and delivery of some of his lines
Emma under commits as Hermione when in the book she's constantly speaking and looking at things from all angles in addition to being a worry wort , and very emotional. Emma on the other hand should have taken it up a notch. When Ron returns we see glimpses of the Hermione as describes in the books shouting at Ron and Harry and taking the LEAD.
Rupert on the other hand nails the Ron role. All the actors/actresses who played a Weasely did a wonderful job. I think he balances the chemistry issues out. He's keeps the characters grounded here. Without him, the film would have been a mess in my opinion. The scenes where it's just Harry and Hermione i.e. the awkward dance. It just felt awkward.
What do you guys think?
