The main thing that disappointed me about this movie was the removal of the final battle scene. That scene really tied the whole book together. Students and teachers and Order all fighting together against the forces of evil. I find it hard to believe that after Bellatrix destroyed the Great Hall no one woke up and defended the castle. The whole ending of the movie just fizzled out. Harry is left alone with Hermione and Ron, with a looming task ahead of him and almost no support from anyone else. It really sucked out the moral of this particular book. .
