Personally I think they've done a heck of a job on the costume so far, and the movie isn't even finished yet. I agree that some of the dialogue seemed a bit clunky but maybe it's cos we're seeing it out of context. I dunno, but you don't seem to be alone in your opinion. I've accepted that these movies follow a certain trend to help appeal to a mainstream audience, I just hope that they treat the source material with respect and so far I don't see a need to worry just yet.
Bring it on
