Thats the thing there is so much in the Gringotts robbery and the final battle because you have DD's brother, you have the meeting of the anti-Carrow squad. You have finding the 5th Horcrux, you have half a battle, you have Snape's life, you have Harry walking into the forest, you have Harry being killed, you have King's Cross, you have Neville killing Nagini and been set on fire, you then have the finale of Harry killing Voldy and then the epilogue.
I really want them to do all of that as well as it should be done. That's not really mentioning Gringotts.
