Harry Potter 6: Random Thoughts. How will they explain the beginning of book 7?

I will add on more as nitpicky and neuro as I am but this has just been bothering me.
How will they kick off movie #7 when they omitted two crucial characters and a significant fight?!
In the ending of book #6 (Half Blood Prince), there is a battle between the death eaters and Dumbledore’s Army. Malfoy had allowed the Death Eaters including Bella and Fenrir the werewolf who has an affinity for small children into the castle (to which Dumbledore says I’m surprised that you would let these monsters into a place where your friends reside which was omitted in the movie. This part was crucial because it showed that Malfoy was working against his will and he does not have to balls to choose either side but he never meant to hurt his friends.)
Anyway, during the battle Bill Weasley is mangled by Fenrir and Fleur Delacur (from the Goblet of Fire) is still insistent that they get married because she loves him for who he is and she’s “pretty enough for the both of them.” In book 7, Harry goes to the Weasley’s and there is a good chunk of the book where they plan their mission all while Mrs. Weasley is trying to distract them and keep them apart. Not to mention, it is at the wedding when they receive news that the Ministry has falle and this marks the beginning of the hiding for all muggles and muggle supporters.
AH! AND Tonks finds Harry in HP6 on the train not Luna! And HARRY hides the Potions book in the Room of Requirement not Ginny! This is KEY. Harry has to hide it because he hides it next to the Hufflepuff Tiara which he has to find in the next book. How is he going to FIND it if he doesn’t have recollection of it?!?
All the characters are developing nicely though. Emma is really pretty.
/rant. Still love the movie tho. I can’t help that I’m a loser.
