It is tough to really get into a movie that you know only covers half the story and the slow half at that. Like the last movie you really need to have read the book to follow the movie. "Prince" didn't spend much time explaining horcruxes and :Hallows" assumes you know what they are and why they are important.
It seems like the director is more interested in getting the movie to be a convenient length rather than using them to expound the story.
If you are into the Harry Potter thing it is a pretty good movie. If not, you have to be one very confused person.
