I thought it wasn't as great as it should've been.
They messed up finding one of the Horcruxes for the seventh movie(s).
I'm talking about how Ginny hid the potions book, when he was supposed to do it himself.
And when he placed it in the room of requirement, the tiara was supposed to be visible.
And they skipped that huge battle at the end.
Also, the movie almost got completely rid of my favorite character...
Neville!
Also, there was a LOT of talking, rather than action, though when Dumbledore cast that fire spell...
That was intense. o.o
Ginny got a lot cuter, and Hermione is, well... Hot.
xD
