Wasn't the Ginny in the books sort-of "just there" too?
WHY DIDN'T THEY MENTION THE HORCRUXES??? Seriously I understand, ok let's cut out the Riddle past etc. but that shit was important! Dumbledore tells Harry that he's looking for Hufflepuff's cup, Nagini, the locket, and possibly an heirloom of Ravenclaw or Gryffindor. Also, what was SUPER important and they cut out with the conversation was that Harry learned in BOOK SIX that the Sword of Gryffindor destroys horcruxes.
