I believe the producers know what they are doing and as long it's ok for JKR I guess it should be ok for all of us...the scenes they took out or changed a little bit are ok...it's true that the house-elf thing is Hermione's business and not Harry's...and I'm also not saying that Hermione isn't important but if they have to choose between what is Harry's business and what is Hermione's business they will opt to choose Harry's business and use that in the film instead...great news once again...thanks!!!
